Question

Solve this equation for x. Round your answer to
the nearest hundredth.
1 = In(x + 4)

Answer 1

x ≈ - 1.28

Explanation:

Using the rule of logarithms

`log_(b)` x = n ⇔ x =
`b^(n)`

Given

ln(x + 4) = 1 , then

x + 4 =
`e^(1)` ( subtract 4 from both sides )

x =
`e^(1)` - 4 = - 1.28 ( to the nearest hundredth )
