Question 251328
(- x^-2 y^3)/(5y-^2)^2 
what does 5y-^2 mean?
repost with correct problem 
Is it 
((a^(-2/3))*(b^(3/4)))*((a^(1/4))*( b^(2/3)))
first convert all fractions to denominator 12
((a^(-8/12))*(b^(9/12)))*((a^(3/12))*( b^(8/12)))
arrange like terms
((a^(-8/12))*((a^(3/12))*( b^(8/12)))*(b^(9/12)))
((a^(-8/12))*((a^(3/12))*( b^(8/12)))*(b^(9/12)))
( b^(17/12)))/((a^(5/12))
