**Helper**, Saturday, February 19, 2011 at 6:31pmJulie, because of formatting please type division problems as follows (using "/" for division).

If this is your problem,

((4y^2)^5)/y^-3

1024y^10/y^-3 = 1024y^13

Subtract the exponents, 10 - (-3) = 13

Or, 1024y^10/(1/y^3)

Invert the denominator and multiply,

1024y^10 * y^3 = 1024y^13

Remember, y^-3 = 1/y^3
