11-28.

Example: Evaluate without the aid of a calculator: $e^{3 \ln 7}$ .
Solution: $e^{3 \ln 7} = \left(e^{\ln 7}\right)^{3} = 7^{3} = 343$ .

Use this idea to solve the following problems.

$e^{3 \ln x}$
Step (a):
$(\textit{e}^{\ln{\textit{x}}})^3$

$\ln e^{5x}$
Step (b):
$5x \ln e$

$\log\sqrt { 10 ^ { x } }$
Step (c):
$\log(10^x)^{1/2}$

$10^{(3+ \log x)}$
Step (d):
$10^3 10^{\log{\textit{x}}}$
