Question

convert the expression from exponential form to radical form.
$x^{7/9}$
$x^{7/9}=\square$

Explanation:

Step1: Recall rational exponent rule

For $x^{\frac{m}{n}}$, it equals $\sqrt[n]{x^m}$

Step2: Apply rule to given expression

Substitute $m=7$, $n=9$ into the rule:
$x^{\frac{7}{9}} = \sqrt[9]{x^7}$

Answer:

$\sqrt[9]{x^7}$
