Question

Find the roots of f(x) = (e x − e π )(e x − π) where e denotes Euler’s number.

Answer 1

The function given to us is:

f(x) = (ex-eπ) (ex-π)

We know that the roots of this equation will be the those values of  that will make the value of the function f(x). Thus, the roots can be found as:

(ex-eπ) (ex-π) = 0

Therefore either, (ex-eπ) = 0 or (ex-π) = 0

Thus, from the first one we will get:  as one root and from the other equation we will get:

x = π/e

for the second root.
