Answer 1

Correct answer is (b) inverse

Explanation: Square root is inverse function of square. The statement can be derived by having a look on the graphs of both square and square root. The nature of graph of square is parabolic and that of square root is rectangular hyperbola. The other method here can be by observing the power which is 2 in case of square and \(\frac{1}{2}\) in case of square root.
