log 9√xy
= log9 + 1/2 logx + 1/2 logy
= 2log3 + 1/2 logx + 1/2 logy
or, maybe you meant the 9th root of (xy), in which case we would have
1/9 logx + 1/9 logy
= log9 + 1/2 logx + 1/2 logy
= 2log3 + 1/2 logx + 1/2 logy
or, maybe you meant the 9th root of (xy), in which case we would have
1/9 logx + 1/9 logy
