Logarithms

If log8=m and log7=n, write each logarithm in terms of m and n:

log(8/49) [fraction, not base]

for this, i put log8-log7-log7 which is m-2n, but the teacher marked it wrong.

log448

for this one, i got 2log8+log7, which is 2m+n, but once again, the teacher marked it wrong.

Are these answers right, or is the teacher wrong?

Re: Logarithms

I'm not sure why the teacher marked that one wrong.

Once again, the teacher must be wrong. These even check out on the calculator, so I'm sure that neither of us have made any mistakes.
