Question 62415
[(x^0y^2)^-2 y^5 x]/ x^2 x^(-5)y y^(-3)

==> [x^0 y^(-4) y^5 x]/ x^2 x^(-5) y y^(-3)   [The first term the powers are multiplied]

==> [x^(0+1) y^(-4+5)]/ [x^(2-5) y^(1-3)]   [ The exponents of the same bases are added]

==> xy / x^(-3) y^(-2)

==> x x^3 y y^2  [multiplying both the numerator and the denominator by x^(3) y^(2)

==> x^4 y^3 [ The exponents of the same bases are added]



Good Luck!!!
