I need to find x in this equation here:

47.81 = 63.466e^0.61119x

....how???

Please actually explain what's going on rather than just giving me the answer too, I'd like to understand what's going on.

Thanks!

Oops, typo. The exponent should be 0.6119x. Not 0.61119x.

I think it should be:
ln 47.81 = ln 63.466 +0.6119x
(ln 47.81-ln 63.466)/0.6119 = x
(ln (47.81/63.466))/0.6119 = x
