Question: Aarnie tried to solve the equation e 4x +e 2x =12 but got the wrong answer. Here is his first step: ln(e 4x )+ln(e 2x

Aarnie tried to solve the equation e^4x+e^2x=12 but got the wrong answer. Here is his first step: ln(e^4x)+ln(e^2x)=ln(12)

Explain why his first step was wrong.

Help Aarnie get a correct solution. Show all steps and write the solution in the box provided using exact form.('Exact' means do NOT approximate logarithms, square roots or fractions with a calculator. For example sqrt2 and ln4 are exact.1.14 and 1.39 are calculator approximations.)
