How do you solve sin(e^x)=0 for x?

The question is "find the smallest number x such that sin(e^x)=0".... but I can't even get AN answer lol!

Much appreciated!

well, sine is zero at zero radians, and at PI radians

e^x=0

because e^x cannot be zero, then

e^x=PI take the ln of each side

x=ln(PI)
