1. The problem statement, all variables and given/known data
125,000=79,770.26(1+[itex]\frac{.045}{n}[/itex])^{10n} 2. Relevant equations 3. The attempt at a solution I'm not sure how to use a logarithm with this, or if it's even possible. I know that n=12, I just don't know how to solve for it.

You can't solve this analytically. You will need to resort to numerical techniques.

Thanks, I wasn't sure if I was missing something. It's not exactly 12 here because the 79,770.26 is rounded.

79,770.62 is closer, and 79,770.63 is closer still for n=12.
