c= In 4
A.) e^c= 4
B.) 4^c = e
C.) c^4= e
D.) e^4 = c

Answer: Choice A) e^c = 4

=====================================

In general if we had something like x = ln(y), then it is equivalent to e^x = y or y = e^x. The Ln is a natural log that is the inverse of the base e exponent. It's a special kind of log.

In this case, x = c and y = 4

So we go from c = ln(4) to e^c = 4

note: Logs are often used to solve for equations with variables in the exponent.
