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
