Question

how do i solve this exponential equation...
e^2x-4(e^x)=0

Answer 1

e^(2x)-4(e^x)=0

Answer 2

Let z = e^x, so z^2 = e^(2x)

So your goal is to solve

z^2 - 4z = 0

Then use the solutions in terms of 'z' to find the solutions in terms of 'x'

Answer 3

still need help?

Answer 4

oh sorry, i understood :) thanks

Answer 5

That's great. What did you get for the answers?
