    \[\implies (4\sqrt{81a^3})^5 \]\[\implies 4^5 \times \left(\sqrt{81a^3} \right)^5\]

    4^5 * 3^5 *a^(15/2) should be 4^5 * 9^5 *a^(15/2)

    that becomes sqrt of 81 a^15?

    no, since you have: (4*sqrt(81*a^3))^5=4^5*(9*a^(3/2))^5=4^5*9^5*a^15*sqrt(a)

    Okay, the fraction exponent is confusing me. I think there is a way without using it, right?
