Question

Rewrite the expression with rational exponents as a radical expression.

Answer 1

Answer:

$7\sqrt[3]{x^2}$

Step-by-step explanation:

The rule of exponents that dictates this to be solved is:

$x^{\frac{a}{b}}=\sqrt[b]{x^a}$

The power of 2/3 is on "x", NOT 7, so we use this property to write it as:

$x^{\frac{a}{b}}=\sqrt[b]{x^a} \\7x^{\frac{2}{3}}=7\sqrt[3]{x^2}$

third answer choice is right,  $7\sqrt[3]{x^2}$

Answer 2

The correct answer to your question is C or the third option
