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.
