Question: can e be raised to a negative number?
Answer: To start, your answer is e^(-x) or exp(-x) is equal to 1/(e^x) or 1/exp(x). ... We can take this idea further to talk about real number exponents (and more), and define a^b, where a and b are any real numbers, as exp(b*log(a)), and of course, a^-b being 1/exp(b*log(a)) (“log” here is the natural logarithm).
