log%28%282%29%29%2Flog%28%2832%29%29

Since 32 = (2)(2)(2)(2)(2) = 25

log%28%282%29%29%2Flog%28%282%5E5%29%29

A rule of lagarithms tells us that we can move the exponent 5
out front as a coefficient of the log:

log%28%282%29%29%2F%285log%28%282%29%29%29

Now we can cancel the log 2's and get

cross%28log%28%282%29%29%29%2F%285cross%28log%28%282%29%29%29%29

which is just

1%2F5

Now do yours the exact same way.
