# Welcome to Algebra I: Power of a Power

13 minutes

(female narrator) Simplify the following expressions. Number 1: 3 to the 9th, all to the 2nd. Number 2: W to the 7th, all to the 5th. Okay, ready to check? Let's see. 3 to the 9th, raised to the 2nd power, that is the same as 3 to the 18th. And W to the 7th, raised to the 5th power, that's the same as W to the 35th. To see how I did those, in case you got something different, here's what I did. So 3 to the 9th, squared, I'm raising a power to another power. So just multiply my exponents together. 9 times 2, that's 18. That means that this simplifies to 3 to the 18th. All done. That next one, I had W to the 7th, raised to the 5th power. So just multiply those exponents together. 7 times 5, that's 35. That means this simplifies to W to the 35th, and you're all done. All right? All right, guys. Hope you've mastered solving problems involving having to raise a power to another power. Apply your rule of multiplying your exponents together, and I'll see you soon for some more Algebra 1. Bye!
