Question 148743
evalueate the log. using the change of base formula. 
log.1/3(.015)
---------------
It looks like you posted the following
log(base 1/3) 0.015
---------------------
If that is the problem, the answer is 
= [log(0.015)] / [log(1/3)]

= -1.82391... / -0.47712....

= 3.82274 when rounded down.
