Solve the equation: e^x-1=0

To solve a simple exponential equation, try to isolate the power portion (e^x) on one side, and the bare numbers on the other. In this way, we discover that when e^x = 1, since taking 1 away from it would yield zero.
e to the power of WHAT would equal one? You can solve this with logarithms, or you can use simple power laws: ANYTHING to the power of zero is one, and therefore x = 0 in this equation.

Cool, thanks, but we can also solved it without using ln right, we can see that every number raise to power of zero is always equal to 1
