Question

How do you solve `lnx=2.7`?

Answer 1

`x\approx 14.88`.

Explanation:

The operation inverse to the logarithm is the exponential.
Then we can apply the exponential on both side of this equation

`ln(x)=2.7`

`e^(ln(x))=e^2.7`

and, because the exponential is the opposite of the `ln` we have

`x=e^2.7\approx14.88`.
