#### Math Question

Sun Sep 10, 2006 10:58 am
I had one question that I don't seem to understand.

Algebra: [(1/5)^m] * [(1/4)^18] = 1/[2(10)^35]
what is m?

Any insight would be appreciated, thanks.

The answer is : m = 35

RHS: 1/2(10)^35 = (1/5^35 )* (1/2^36)
= (1/5^35) * (1/4^18)

equate on both sides and woyla you get m = 35. Correct?
