Oh, you did just plug in right? Just backwards? He told us the answer I just wasn't sure how to find the answer, but that helps. Thanks!
Wait, are we allowed to distribute the ^6 to make it a^2b^3? How did that happen?
Okay, just looked at it. (a^1/2)^6 equals a^3 because we add the exponents right? And same for b^1/3. Okay, got it. Thanks!
