all you had to do was add two numbers given, and double it, and put the neg sign in front.

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!

I'm inclined to say .7 but it just a guess.
