    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!
