SOLUTION: I need help with trying to simplify with a postive exponent. The problems have large curved braces on both sides and a line separating the lower part. (4x) ^-3= y^3 (-a^2

Question 349123: I need help with trying to simplify with a postive exponent.
The problems have large curved braces on both sides and a line separating the lower part.
(4x) ^-3=
y^3

(-a^2b) ^3
2b^-1

.(3xy-^2) ^2
x^3

Multiply NUM and DEN by (4x)^3
=
=
-----------------------

=
Multiply NUM and DEN by b
=
---------------------
(3xy-^2)^2/x^3
----------
y-^2 isn't right.
