**Clare**, Monday, April 16, 2012 at 7:37pmPlease simplify completely :)

**Reiny**, Monday, April 16, 2012 at 8:05pm100/64 = 25/16

x^3 / x^7 = 1/x^4

y^-2 / y^4 = 1/y^6

so (100x^3y^-2)/(64x^7y^4)

=25/(16 x^4 y^6)

**Clare**, Monday, April 16, 2012 at 8:26pmwait isn't (y^-2)/(y^4)=y^2?

**Reiny**, Monday, April 16, 2012 at 9:14pmnope

(y^-2) times y^4 would be y^2, but you were dividing, so you have to subtract the exponents

-2 - 4 = -6
