Question

E^x not equal to zero

Answer 1

`e^x \\eq 0`

Explanation:

We will prove this with the help of a contradiction:

Let as assume that
`e^x = 0`

Multiplying both sides by
`e^(-x)`

`e^x* e^(-x) = 0* e^(-x)\\e^0 = 0\\1 = 0`

which is not possible.

Hence, our assumption was wrong which led us to a contradiction.

Thus,

`e^x \\eq 0`
