hi, There is a typo in the question. http://www.beatthegmat.com/gmatprep-exponents-t8855.html Heres how I solved it. (1/5)^m * (1/4)^18 = (1/2) *(1/10)^35 (1/5)^m * (1/2 *1/2)^18 = (1/2) * [(1/5 *1/2)]^35 (1/5)^m * (1/2)^18 * (1/2)^18 = (1/2) * (1/2)^35 * (1/5)^35 (1/5)^m * (1/2)^36 = (1/2)^36 * (1/...

Hi diebeatsthegmat,
Thats exactly my question. I fail to understand if its a simple or compound interest problem.
The answer given says its a compound one, but the explanation they have given is too vague to make anything out of it.
