Solve X with e
Solve for x:
ln(x+3)=6
Can you explain to me how the answer is e^(6) -3
Thank you

Re: Solve X with e
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?

I did it on a calculator first then tried on my own and became very confused.

Re: Solve X with e
Im sorry, the e concept has me very confused. I feel like Ive wasted a lot of time on these type of examples on my own.

Re: Solve X with e
Well let me see again...
That then takes me to the next step of
x+3=e^6

Re: Solve X with e
Correct! Now you just subtract 3 from both sides and you're done!
