Question

Simplify
(-4xy^7 y^-3)^2
(---------- )
(-3x^-3y^-3 )

Answer 1

\[-\frac{16}{3} x^5 y^{11} \]

Answer 2

If this is a division, then you get:

(-4xy^7/y^3)(-4xy^7/y^3)/(-3/x^3y^3)
(-4xy^7/y^3)(-4xy^7/y^3)(x^3y^3/-3) = -16x^5y^11/3

Answer 3

gw2011,
We both agree on the answer.

Answer 4

robtobey--you,re right, so there is at least strength in numbers
