Choose a random x and compute (exp x)*(exp (-x)) with a spreadsheet. What do you get? How about (exp 3x)*(exp (-x))3?
Solution for (exp x)*(exp (-x)):
My random choices are 1 and 3. For 1, I get exp 1 = 2.718281828, exp(-1) = 0.367879441, and product 1. For x = 3, I get exp 3 = 20.08553692, exp(-3) = 0.049787068 and the same product.
Solution for (exp 3x)*(exp (-x))3:
I find, for x = 1, the answer 1. You try something.
