PRINCIPAL SHANKAR BAGDE’S METHOD OF SQUARE ROOT

If n is non zero integer, then n x n written as n2 is called square of n. Hence square of a number can be found by multiplying it by itself. Only perfect squares have square roots, finding the squre root is just inverse operation to finding the square.Every natural number does not has a square root.No number multiplied by itself gives 57, so 57 does not has a square root.Only perfect squares have squre roots.
