## rudedawg Group Title having trouble figuring out how to solve this. e^(x-5)=(1/e^4)^(x+2) one year ago one year ago

1. GOODMAN Group Title

Try taking the ln of each side so you can get the exponents down.

2. rudedawg Group Title

so we have (x-5)ln e=(x+2)ln (1/4e^4) after this what is our next step?

3. TuringTest Group Title

you have to be careful in simplification here$(x^a)^b=x^{ab}$and$\frac1{x^a}=x^{-a}$so$\large (\frac1{e^4})^{x+2}=(e^{-4})^{x+2}=e^{-4(x+2)}$now try with the log...
