Evaluating exponential function

[K_Swiss]

Evaluate $\displaystyle e^{2ln4}$ using properties of the logarithm.

I used a calculator to solve this question and I got 16, but I don't know how to solve this without a calculator... Please help?

It's easy using the properties of logs. Remember that e 'cancels out' ln because e is the base of ln.

$\displaystyle e^{2ln(4)}=e^{ln(4^{2})}=4^{2}=16$

See?.
