    e^(5x)=25 take ln( ) of both sides

    This is so you can bring down the (5x) part

    Well have you taken the ln( ) of both sides as I suggested ?

    \[e^{5x}=25 \\ \ln(e^{5x})=\ln(25)\] now just use power rule on the left hand side bring down the 5x in front of the ln(e) and recall ln(e)=1

    But if you can't read it: 1st step: take ln( ) of both sides 2nd step: use power rule so you bring the 5x thing 3rd step: use that ln(e) is 1 4th step: just divide both sides by what x is being multiplied by.
