6 = ln (x + 4) For this case, the first thing to do is to use the exponential for both sides of the equation. We have then: exp (6) = exp (ln (x + 4)) Rewriting we have: exp (6) = x + 4 Clearing x: x = exp (6) - 4 Calculated: x = 399.4287935 nearest hundreth: x = 399.43 Answer: The value of x is: x = 399.43
