# Thread: Exponents and Log Help!!

1. ## Re: Exponents and Log Help!!

Top part: indeed
Second exercice: that's not correct.
Write:
$\left(4a^{\frac{5}{3}}\right)^{\frac{3}{2}}=\left( 4^{\frac{3}{2}}\right)\cdot\left(a^{\frac{5}{3}} \right)^{\frac{3}{2}}$ $=8\cdot a^{\frac{5}{2}}$

Do you understand everything now? Or is it not clear? ...
It's really important that you know al these basic rules!

Ohh, I get it now, the $a^{\frac{5}{3}$ didn't apply to the 4, just the 3/2. Thank you very much!

hi guys

i think that the first one was:
(5a^2)/3*(4a^3)/2
