Question 668732: The value, V, of a bank account in which A dollars are invested at 5% interest compounded annually, is given by the equation V = A(1.05)^t, where t is the time in years. Solve for t.
I'm really struggling with this question - not even sure where to start. I think I might have to take the log of each side, but I'm not sure how to do that. Any help would be apprecieated.

V+=+A%281.05%29%5Et

V%2FA+=+1.05%5Et

log_%5B1.05%5D_%28V%2FA%29+=+t
