Answer
$$\lim_{x\to0}\frac{\ln(1+x)}{\cos x+e^x-1}=0$$
Work Step by Step
$$A=\lim_{x\to0}\frac{\ln(1+x)}{\cos x+e^x-1}$$
As $x$ approaches $0$, $\ln(1+x)$ approaches $\ln(1+0)=\ln1=0$ and $(\cos x+e^x-1)$ approaches $\cos0+e^0-1=1+1-1=1$
So this is not an indeterminate form, but another with which we can replace $x=0$ right away.
$$A=\frac{\ln(1+0)}{\cos0+e^0-1}$$
$$A=\frac{0}{1}$$
$$A=0$$
