Learn how to solve limits by direct substitution problems step by step online. Find the limit of log(x+4) as x approaches 4. Change the logarithm to base e applying the change of base formula for logarithms: \log_b(a)=\frac{\log_x(a)}{\log_x(b)}. Evaluate the limit \lim_{x\to4}\left(\frac{\ln\left(x+4\right)}{\ln\left(10\right)}\right) by replacing all occurrences of x by 4. Add the values 4 and 4.

Final answer to the problem

$\frac{\ln\left(8\right)}{\ln\left(10\right)}$
