Question

which exponential expression is equivalent to please help

Answer 1

Answer: Choice D  $c^{5/7}$

Explanation:

The rule we use is

$\left(\sqrt[n]{x}\right)^m = x^{m/n}$

The denominator n is the index of the root

With that rule in mind, we can say

$\left(\sqrt[7]{c}\right)^5 = c^{5/7}$
