Representing Radicals with Exponents refers to expressing a radical expression as an expression with a fractional exponent.
The general form is \$a^(1/n) \$​

Here, \$ n\sqrt(a)​ \$ (the radical form) is equivalent to \$ a^(1/n) \$​ (the exponent form), where: a is the radicand.
n is the index of the radical, which becomes the denominator of the exponent.

Explanation: The image shows how to write radicals with exponents:

\$ a^(1/2) = (\sqrt a) \$​ (square root).

\$ 64^(1/2) = (\sqrt 64) ​= 8 \$ (example: square root of 64 is 8).

\$ a^(1/n) = n(\sqrt a) \$​ (n-th root).
