ANSWER

False

EXPLANATION

If


a

is a real number and m and n are positive integers, Then,


{a}^{ (m)/(n) } = \sqrt[n]{ {a}^(m) } = ({ \sqrt[n]{a} })^(m)


{a}^{ (m)/(n) } \\e \sqrt[n]{ {a}^(m) } \\e ({ \sqrt[m]{a} })^(n)

For instance,


{8}^{ (2)/(3) } = \sqrt[3]{ {8}^(2) } = ({ \sqrt[3]{8} })^(2) = 4


{8}^{ (2)/(3) } \\e\sqrt[2]{ {8}^(3) } \\e ({ \sqrt[2]{8} })^(3) \\e4
