Hi Marta,

The opposite mathematical concept of a logarithm is an exponent.

Therefore, when you are observing a relationship which is exponential, you can apply a log transformation to reach a linear relationship.

Alternatively, if you are observing a log transformation, you can apply an exponential transformation to reach a linear relationship.

Note that a linear regression requires a linear relationship and that is why we are trying to achieve it!

Best,
