Question

Find the value of x for exp(3x)=e ?

Answer 1

See explanation below

Explanation:

They are asking for a solution of `e^(3x)=e^1=e` (1)

However, `e^x` is an injective function, that means: the exponents have to be equal, so the expression (1) would be true if and only if `3x=1`.

And this is true if `x=1/3`.

So, the solution is `x=1/3`
