I have been working on these problems and I must have a logic problem, could you put me in the right direction? Here is the problem and what I have done:

If A=2, B=3, C=5 I am supposed to evaluate the following:

ln(A^3/B^-3C^3)

ln(A^3)-ln(B^-2)-ln(C^3)

3lnA + 2lnB - 3lnC

3ln(2) + 2ln(3) - 3ln(5) = -5516476183

The back of my calc book tells me the answer is incorrect, could you let me know where I went wrong.

Thank you!!!!!!!!!!!!!!!!!
