Is there an x such that e^x = 0?

hi,
i have a question.

e^x =0
is this possible, and for what values of x if so.?

No.

If you understand the idea of limits you can say that e^x approaches 0 as x approaches negative infinity

\lim_{\substack{x \rightarrow - \infty\\}} e^x = 0

The larger and larger negative numbers you get for x, the closer and closer to zero you will get for e^x. But you can never actually get 0.

For more help, you can draw the graph of e^x , the graph is an increasing function and which approaches zero and -infinity, but never equals zero.
