Question

This is NOT multiple choice

Solve the equation 15e^4x = 12 for x

Show your work please

A) identify the exact solution

B) approximate the solution to the nearest thousandth.

Answer 1

Explanation:

15 e^(4x) =12

divide both sides by 15

e^(4x) = 0.8

if e^y = X

then y = ln x

4x=ln 0.8

4x=-0.22314

dividing both sides by 4

4x/4= -0.22314/4

x = -0.0558
