log_(1/4)〖1/64〗+log_2〖1/32〗log_9〖(75+x)〗log_279=(14)/3

math 
Steve,
1/4 ^3 = 1/64
2^5 = 1/32
what's the base for log 279?
I think you may have meant log_9 729 (9^3 = 729)
Assuming that,
3  5  log_9(x+75)  3 = 14/3
log_9(x+75) = 1/3
At this point, you can still solve it, but the answer is not as simple as it ought to be, judging from the problem. Check for further typos.
