Question 930418: Approximate the following logarithm using the properties of logarithms given.
logb(2)=0.216
logb(3)=0.343
logb(5)=0.502
logb(25b^2)=???
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
log(25b^2) = log(25) + 2log(b)
----
log(25b^2) = log(5^2) + 2
= 2log(5) + 2
= 1.004 + 2
= 3.004
