Would someone mind double checking my work. Everytime I think I have a good grade, it turns out to be alot lower than I thought it would be.
1. x^2 y^-3 z ^-5 / x^-4 y ^ 3
= x^2 x^-4 z^-5/y^3 y^-3
= x^-2 z ^-5/y
2. 36x^2 y^5 z^3 (all of this is cubed by the square root)
= 6x^6 y^15 z^9
3. 4x^2 times the square root of x^5 y^2/ the square root of 2xy
= 4x^10 y^4/2xy
= 2x^9 y^3[/code]
