Log75+Log9/Log 45
It's not often you divide logs, but what the heck ...
log75+log9 = log(75*9) = log675
log675/log9 = log9675
I suspect a typo, and will note that
log75+log9-log45 = log(75*9/45) = log15
log75+log9 = log(75*9) = log675
log675/log9 = log9675
I suspect a typo, and will note that
log75+log9-log45 = log(75*9/45) = log15
