Answer :

Problem

Solution

We have the following equation given:

3 ln x= -12

We can divide both sides of the equation by 3 and we got:

ln x= -12/3

ln x = -4

Now we can apply the inverse operation of the ln who is exponentiation with base euler (e) and we have:

e^(ln x) = e^(-4)

If we simplify we got:

x= e^(-4) = 0.018
