Question 40433
ll^log11x = x
ln^ex = x
e^lnx =x

You will see the meaning of these answers if you understand
that "log" or "ln" means exponent or power.

In the 1st problem you are raising 11 to the power of 11 that
gives you x.  You therefore get x as the answer.

The same reasoning results in each of those answers be "x".
