Question

The parenthesis is supoose to be around the line as well as the four. I just don't know how to make my computer do that. This is what I get. Can some check to see if it is correct please???

(6xy)-3

(4)as this should be in parenthesis too

(6xy)-3
------ (6x)-3
y-3 =

or 1
--- 3
216 x

x-a=1/xa

or either this way ===>

1/216x^3

(6x/y)^-3
(6x)^-3
(1/6x)^3
1/216x^3

Answer 1

(6xy)^-3 = 1 / (6xy)^3 = 6^3x^3y^3 =
216x^3y^3.
