X=4 in the equation e^lnx = 4. Why is this so? Can you go through the steps/rules

e^ (ln x) is just plain x

Step-by-step explanation:

The functions f (x) = e^x and g (x) = ln x are inverses of one another. In other words, one "undoes" the other.

Thus, as the rule goes, e^ (ln x) is just plain x.

Here, e^ (ln x) = 4 simplifies to x = 4.
