Question

7. Which expression is the exponential form of 3√m

Answer 1

Rewrite the rational (fraction) exponents using the formula ^n√a^x= a x/n

3m 1/2 

Answer 2

Reemmber
$\sqrt[n]{x^c}= x^\frac{c}{n}$

if you meant $\sqrt[3]{m}$, then the answer would be $m^\frac{1}{3}$

if you meant 3√3, then that is $3\sqrt[2]{m^1}= 3m^\frac{1}{3}$
