ab/y

OpenStudy (saifoo.khan):

$\frac{ax^2}{b} \times \frac{b^2}{x^2y}$

OpenStudy (saifoo.khan):

$\frac{ab}{y}$

ab over y is right.... |dw:1319686884954:dw|

Thanks everyone. I thought it was ax over y... doesn't the 2 b's cross each other out?

OpenStudy (anonymous):

The two b's don't cross each other out because b^2 is a part of the numerator and b is a part of the denominator. If you cross out the b from the denom, and one b from the numerator, you still have one b left :)

k, gotcha. thanks again :)
