Evaluate the expression: lne^e

OpenStudy (anonymous):

ln e 0 e 1

hartnn (hartnn):

first use the property of the log that \(\Large \ln a^b = b \ln a \)

hartnn (hartnn):

then you can simply plug in ln e =1

OpenStudy (anonymous):

so the answer is 1?

OpenStudy (anonymous):

or 0

hartnn (hartnn):

no, did you first use the porperty i gave ?

hartnn (hartnn):

\(\ln a^b = b \ln a \\ \ln e^e = ... ?\)

OpenStudy (anonymous):

honestly dont get that formula haha

OpenStudy (anonymous):

wait lne^e = elne

hartnn (hartnn):

yes, correct! and with ln e = 1 what do u get ?

OpenStudy (anonymous):

OpenStudy (anonymous):

which = e

hartnn (hartnn):
