Question

e^(11 x -13) = 9
Find the exact value of x. No decimal entries.
I got ln(9+13)/11 what did I do wrong?

Answer 1

\[e^{11x-13}=9\]\[\ln(e^{11x-13})=\ln(9)\]\[11x-13=\ln(9)\]Do you see now?

Answer 2

You take the natural log of both sides, getting rid of the e, so now I solve from here?

Answer 3

I still get the same answer ln(9)+13/11

Answer 4

\[\frac{\ln(9+13)}{11}\]Is the not the same as:\[\frac{\ln(9)+13}{11}\]

Answer 5

ln(9+13)/11

not the same answer.

Answer 6

Now I see my mistake thanks guys
