Question

Which of the following represents fifth root of x squared in exponential form?


x to the 2 fifths power
x to the 5 over 2 power
5x2
2x5

Answer 1

the exponent should be
\[\large \frac{2}{5}\]

Answer 2

Using the rule

\[\Large \sqrt[n]{x^m} = x^{m/n}\]

we can say

\[\Large \sqrt[5]{x^2} = x^{2/5}\]
