I need help with this plz

Answer 1

Answer:

$x^{15}$

Step-by-step explanation:

Distribute the ^3 on top

(27 $x^{6}$ $y^{-9}$)

distribute the ^ -9 on bottom, only to what is in the parenthesis

(27 $x^{-9}$ $y^{-9}$)

the 27's cross out, the $y^{-9}$ 's cross out

$x^{6}$/ $x^{-9}$ is left

move the  $x^{-9}$ to the top of fraction to change its sign

$x^{6}$ · $x^{9}$ = $x^{15}$
