How do I get x^(e^(x-1)) from (x^e^x) divided by x?

And what is a good website where I can find laws for exponents/natural e?

    By exponential property, x^(e^(x))/x can be written as...

    x^(e^(x)) * x^(-1)

    = x^(e^(x) - 1)

    BUT you can't get x^(e^(x - 1)) since you are not multiplying exponents in this manner..

    I hope this helps!

    You don't because this is wrong.

    If yoou let, for the time being, e^x=y, then

    you have x^y/x=x^(y-1)=x^(e^x-1) and not x^(e^(x-1))=x^e^x/e.

    The following site does a reasonable job of

    explaining why exponents work the way they do.
