(5z^3w/-6m^3)*(-6m^5/25z^9)

(OR)

5z^3 -6m^5

------ * --------

-6m^3 25z^9

Perform the Operations and Simplify[/QUOTE]

It's a Multiple Choice.

a)wm^2/5z^5

b)wm^2/5z^6

c)z^3wm^5/5z^9m^3

d)none of the above

I chose (D) because the way I did my math I came up m having a power of 8. I feel like I'm wrong here.

My solution: (1/5)m^8wz^12

**drwls**, Thursday, May 1, 2008 at 9:17pmYou forgot the w in your "OR" version. Your answer is wrong in any case. The ratio of the powers of m results in m^2.

The correct answer is (b)
