<PRE><B>Question 172575</B>
approximate the following logarithms using the properties of logarithms given logb2=0.3562,logb3=0.5646,logb5=0.8271:
-------------------------------------------- 
logb(2/5) = logb(2)-logb(5)
--------------------------------
logb(5b) = logb(5) + logb(b) = logb(5) + 1
--------------------------------
logb(30) = logb[2*3*5] = logb(2) + logb(3) + logb(5)
---------------------------------
I&#39;ll let you do the substitutions and the arithmetic.
==================================
