Question

Solve the equation by using the basic properties of logarithms. ln(x+4)=-1

Answer 1

Answer:

-3.63

Step-by-step explanation:

Answer 2

Write both sides as powers of $e$:

$\ln(x+4)=-1\implies e^{\ln(x+4)}=e^{-1}\implies x+4=e^{-1}$

since $b^{\log_ba}=a$. Then

$x=e^{-1}-4\approx-3.63$
