Homework Help: Logarithms

Posted by Amy on Tuesday, September 4, 2012 at 8:34pm.

I need help evaluation the following:

1.) (1/15)^2.309

It says hint: set the expression = x and take the logs of both sides.

I did: x=(1/15)^2.309
logx = log(1/15)^2.309 = 2.309 log(1/15)
and I don't know how to proceed or if I'm on the right track.

2.) Find the base x for which
logx (4.44 * 10^4) = 4.44

Hint: write the corresponding exponential expression.

I did 4.44^x = (4.44 * 10^4)
