### 14.47

Hi,
I'm solving for number 47 and I get that lnQ=15, which is the same answer in the solutions manual. Now solving for Q I get e^15. I do not understand how the solutions manual got Q=10^6 as an answer? Even if you write lnQ as Log(base10)Q, you would get that q=10^15 not 6. Can anyone explain please?

The inverse function of natural log is e. The natural log of Q= 15 so when you isolate Q you get e15= 106.

It really equals 3,269,017 which is a 106 value.
