Steps to do this problem.
(1) The base of the exponent becomes the base of the log.
(2) The answer goes inside the log.
(3) What remains is the answer.
Step #1 is the most important and the most easy to remember.
"The base of the exponent becomes the base of the log.
In this case, the base of our exponent is e.
log [base e] (?) = (?)
"The answer goes inside the log."
The answer on the right hand side, 47, now becomes part of the log.
log [base e] (47) = ?
"What remains is the answer."
The exponent is what remains, and hence becomes the answer to the log.
log [base e] (47) = x
Remember that log [base e] has a special name: ln
ln (47) = x

log e 47=x

e^x = 47
log(e)47 = x
x = ln(47)

e^x=47
when u want to bring the exponent to the right side, u have to ln right side..then x will be brought down...
x=ln 47
