Solve for x:

ln(x+3)=6

Can you explain to me how the answer is e^(6) -3

Thank you

Have you tried doing this:

ln(x+3)=6, so

e[sup]ln(x+3)[/sup]=e[sup]6[/sup]

I just raised the number e to both sides, so that we can get rid of the logarithm in the next step.

Can you do it from here?

Well let me see again...

That then takes me to the next step of

x+3=e^6

Correct! Now you just subtract 3 from both sides and you're done!
