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}
