### About this unit

We previously learned about integer powers—first positive and then also negative. But what does it mean to raise a number to the 2.5 power? In Algebra 2, we extend previous concepts to include rational powers. We'll define how they work, and use them to rewrite exponential expressions in various ways.### Learn
