Answer 5

yeah

Answer 6

oh ok, so then the answer i gave u shld be right

Answer 7

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

Answer 8

simplify

Answer 9

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

Answer 10

that becomes sqrt of 81 a^15?

Answer 11

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)

Answer 12

so confusing! >.<
