Divide both sides by 11.
e^x = 11
Then take the natural log (ln) of both sides. Any good scientific calculator can do this.
ln(e^x) = ln(11)
x = ln(11)

11e^x = 121; divide both sides by 11
e^x = 11; convert to a natural logarithm
ln 11 = x; x is the exponent you must put on e to equal 11
x = approximately 2.398

11e^x = 121
divide by 11
e^x = 11
change into logarithmic form
log_e 11 = x
but log_e z = ln z, so
x = ln 11

you mean 11*e^x=121
then e^x= 121/11=11
then ln(e^x)= x= ln 11=2.397
therefore x= 2.397

11(e^x) = 121
e^x = 11
x = ln(11)
x = about 2.3979

Use the natural logarithm.
