Re: e^-ln(x)

What do you know about numbers and exponents to those numbers?

Let t be any real number. What can you do with e$$^{-t}$$ ?

Re: e^-ln(x)

Well perhaps a way of verifying your answer would be to note -ln(x) = ln(1/x); therefore, e^-ln(x) = e^ln(1/x). Another way is to note e^-ln(x) = 1/e^ln(x).
