i believe this reference answers your question.

generally speaking, you are transforming y = 10 * e^x into the equation ln(y) = x + ln(10)

that's done in the following manner:

start with y = 10 * e^x)

take natural log of both sides to get:

ln(y) = ln(10 * e^x)

this becomes:

ln(y) = ln(10) + x * ln(e) which becomes:

ln(y) = ln(10) + x

rearrange the terms to get:

ln(y) = x + ln(10) which is in the form of a linear equation.

i don't pretend to understand what they doing or why they're doing it, but the reference i found on the web should be helpful.
