## Exercise 2.4

Choose a random $x$ and compute $( exp ⁡ x ) * ( exp ⁡ ( − x ) )$ with a spreadsheet. What do you get? How about $( exp ⁡ 3 x ) * ( exp ⁡ ( − x ) ) 3$ ?

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 $( exp ⁡ 3 x ) * ( exp ⁡ ( − x ) ) 3$ :

I find, for $x = 1$ , the answer 1. You try something.
