# Chapter 7 - Section 7.2 - Rational Exponents - Exercise Set: 23

$\sqrt[5] (2x)^{3}$

#### Work Step by Step

We know that $a^{\frac{m}{n}}=\sqrt[n] (a^{m})$ (where m and n are positive integers greater than 1 with $\frac{m}{n}$ in simplest form and $\sqrt[n] a$ is a real number). Therefore, $(2x)^{\frac{3}{5}}=\sqrt[5] (2x)^{3}$.
