8-104.

Evaluate each expression without using a calculator.

1. $\operatorname { log } ( 10 )$

Remember that $\text{log}\left(x\right)$ is the same as $\text{log}_{10}\left(x\right)$.

$1$

1. $\quad \operatorname { log } ( \sqrt { 10 } )$

$\log\sqrt{10}=\log10^{1/2}$

1. $\operatorname { log } ( 0 )$

$10^{?} = 0$

1. $10 ^ { ( 2 / 3 ) \operatorname { log } ( 27 ) }$

$10^{(2/3)\log(27)}=10^{\log(27^{(2/3)})}$

$9$
