Question
**Evaluate \( 8^{\frac{5}{3}} \)**

This expression involves calculating the power of 8 raised to the fraction \(\frac{5}{3}\). First, recognize that \( 8^{\frac{5}{3}} \) can be broken down into \((8^{\frac{1}{3}})^5\).

Steps to Solve:
1. **Find the cube root of 8**: 
   \[
   8^{\frac{1}{3}} = 2
   \]
   because \(2^3 = 8\).

2. **Raise the result to the 5th power**:
   \[
   (2)^5 = 32
   \]

Thus, the evaluation of \( 8^{\frac{5}{3}} \) is 32.
