SQUARES AND SQUAREROOTS
In this lesson, students link the geometric concepts of side length and area of a square to the algebra concepts of squares and squareroots of numbers. They create a table of perfect squares. They use the table to find squareroots of perfect squares, and they approximate the square root of a whole number.
= 3 √ − 81 = Undefined
The final example, √ − 81 is currently undefined as negatives have no square root. This is because if we square a positive or a negative, the answer will be positive. Thus we can only take squareroots of positive numbers. In another lesson we will define a method we can use to work with and evaluate negative squareroots, but for now we will simply say they are undefined.

WHAT ARE SQUAREROOTS & CUBE ROOTS?
If you know the area of a square, you can take the square root to find its side length. If you know the volume of a cube, you can take the cube root to find its edge length.

In order to multiply roots, they must first be simplified to make the process easier.
Simplifying multiplied radicals is pretty simple. Use the fact that the product of two radicals is the same as the radical of the product, and vice versa.

Corollary 3.13 The following problem is in FP FacRoot ⊆ PPA: given n > 2, find an a coprime to n which is a quadratic nonresidue modulo n.
Proof: If n is a power of 2, we can return 3. Otherwise, we can write n = 2 e m 2 k , where m is odd and not a perfect square. By Theorem 3.12, we can find a such that (a|m) = −1. By adding m to a if necessary, we can make sure a is odd, hence (n, a) = 1. Since a is a quadratic nonresidue modulo m | n, it is also a nonresidue modulo n. Another problem we are going to reduce to FacRoot is the computation of squareroots modulo n. A priori it is not clear how to formulate it as a total NP search problem, as the quadratic residuosity problem is neither known nor assumed to be poly-time decidable. We can remedy this by requiring the search problem to find something sensible also for quadratic nonresidues.

Data Transforms: Natural Logarithms and SquareRoots
Parametric statistics in general are more powerful than non-parametric statistics as the former are based on ratio level data (real values) whereas the latter are based on ranked or ordinal level data. Of course, non-parametrics are extremely useful as sometimes our data is highly non-normal, meaning that comparing the means is often highly misleading, and can lead to erroneous results. Non-parametrics statistics allow us to make observations on statistical patterning even though data may be highly skewed one way or another. However, by doing so, we loose a certain degree of power by converting the data values into relative ranks, rather than focus on the actual differences between the values in the raw data. The take home point here is that we always use parametric statistics where possible, and we resort to non-parametrics if we are sure parametrics will be misleading.
(3) If H 1 and H 2 are two graphs of girth at least 6 such that H 1 2 and H 2 2 are isomorphic, then H 1 and H 2 are isomorphic.
The key idea behind (1) and (2) is that each maximal clique of the square corresponds to the neighbourhood of some vertex in the root. This fails in the case of roots of girth 6.

ORDER AND SQUAREROOTS IN HERMITIAN BANACH *ALGEBRAS P.G. SPAIN
Dedicated to the Memory of Professor Bela Szokefalvi-Nagy
Classical results of Lowner, Sherman, Topping and Ogasawara are extended to unital hermitian *normed Banach *algebras. A new norm condition is presented for such an algebra to be C equivalent.
A cryptosystem, based on computation of squareroots of complex integers modulo composite n, is described in this paper. This paper provides an algorithm extracting a square root of Gaussian integer. Various proper- ties of squareroots and a method for finding Gaussian generators are demonstrated. The generators can be instrumental in constructing other cryptosystems. It is shown how to significantly reduce average complexity of decryption per each block of ciphertext.
Participants were first given a piece of homework consisting of questions where the concept of square root was likely to be employed. The mathematics questions were designed so that they would bring to the surface the ambiguities and inconsistencies of this concept and its associated symbol. The participants were then invited to talk to each other about how they solved/answered the questions set. During the discussion, implications for teaching about squareroots arose naturally, either through the participants’ reflection on how they had been taught the topic or how they would teach the topic themselves. Immersion of the participants’ mathematical work in the pedagogical space was taken further through another task, namely fictional pupils’ scenarios. The participants were asked to give written feedback to three fictional pupils’ responses (Emma-KS3, Peter-KS4 and Lucy-KS5) characterised by a subtle mathematical error in a question involving the square root, throwing further light on the choices the participants made about treating this concept.
of the relations Eqs. (6) and (7) between the parent and the child system, obtained by iteration of a tight- binding equation with couplings T ml between cells m and l. Additional bands can be created by increasing the period in the child system, so that the unit cell en- compasses more components. Alternatively, one could shift the spectrum of the child to positive energies and take additional squareroots, effectively generating poly- nomials of higher order. The unifying key feature in this general one-dimensional setting is the observation that the square root operation allows to replace lattice sym- metries by spectral symmetries, and that these can be interpreted as fractional lattice translations, as described in Sec. II B.
In this paper we introduce a family of weakly contractive maps on the space B(S) of bounded real valued functions and use it to show that a fundamental step in the proof of the well-known Stone-Weierstrass approximation theorem can be achieved via Rakotch’s ﬁxed point theorem for weakly contractive maps. With the same technique, we obtain Zemanek’s theorem on the existence of squareroots in certain Banach subalgebras of B(S), and, ﬁnally, in the context of abstract Banach algebras, we exhibit some relationship between weakly contractive maps on the closed unit ball and the geometry of the spheres.

Abstract. A special class of recurrent neural network, termed Zhang neu- ral network (ZNN) depicted in the implicit dynamics, has recently been proposed for online solution of time-varying matrix squareroots. Such a ZNN model can be constructed by using monotonically-increasing odd ac- tivation functions to obtain the theoretical time-varying matrix squareroots in an error-free manner. Different choices of activation function arrays may lead to different performance of the ZNN model. Generally speaking, ZNN model using hyperbolic sine activation functions may achieve better per- formance, as compared with those using other activation functions. In this paper, to pursue the superior convergence and robustness proper- ties, hyperbolic sine activation functions are applied to the ZNN model for online solution of time-varying matrix squareroots. Theoretical analysis and computer-simulation results further demonstrate the superior perfor- mance of the ZNN model using hyperbolic sine activation functions in the context of large model-implementation errors, in comparison with that us- ing linear activation functions.
