Question

index form of square root of a​

Answer 1

Answer:

Finding square roots and converting them to exponents is a relatively common operation in algebra. Square roots, which use the radical symbol, are nonbinary operations — operations which involve just one number — that ask you, “What number times itself gives you this number under the radical?” To convert the square root to an exponent, you use a fraction in the power to indicate that this stands for a root or a radical.

Answer 2

Answer:

The square root is actually a fractional index and is equivalent to raising a number to the power 1/2. Fourth root: 4x (power 1/4) and so on. See more at Fractional Exponents.
