Question

What is 1n? And evaluate 1n e^3.

Answer 1

that is ln (lower case L)
stands for natural log

or log_base_e
\[ ln(x) = log_e(x) \]

Answer 2

Alright, and how do you evaluate ln e^3?

Answer 3

Natural log and e to a power are inverse functions to each other... they undo each other.
\[\log_{10} 10^{3}=3\]\[\ln e ^{3}=3\]

Answer 4

\[\log_{4} 4^{12}=12 \] As long as the base in the logarithm matches the base in the exponential, the answer is the exponent.
