I have no idea what the answer to this problem is, I'm given choices but I'm still lost. Given: log sub a 2=.4, log sub a 3 =.5, log sub a 5=.8 what is log sub a .01?
a)0.7
b)-0.6
c)1.44
d)-2.4
Please Help!


loga 10 = loga2 +loga5 you are given both of those. Calculate it.


loga .01 = loga (10^-2 = -2 loga 10

So what is -2*loga 10 ?
