log 10.5
Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! find the logarithm of each using log2=.30,log3=.48 and log 7=.85
log 21 = log(3*7) = log(3) + log(7)
-----------------------------
log3^5 = 5*log(3)
------------------------------
log 10.5 = log(3*7/2) = log(3)+log(7)-log(2)
