GMAT Help!
Hi, I am stuck on the solution for this problem. Can anyone help??
(1/5)^m * (1/4)^18 = 1/2(10)^35
Need to solve for m. I know the answer is 35...just need to how the math works out. According to the makers of the test, it should only take a few minutes. What am I missing?? Thanks!!

I assume the original expression is
$\displaystyle \left(\frac{1}{5}\right)^m \cdot \left(\frac{1}{4}\right)^{18}= \frac{1}{2 \cdot 10^{35}}$
rewrite as ...
$\displaystyle 5^{m} \cdot 2^{36} = 2^{1}(2^{35} \cdot 5^{35})$
should be easy to "see" what m is now.
