Use the log laws to write the following as a single log.

1. $\operatorname { log } 4 + \operatorname { log } 2 - \operatorname { log } 5$

   Answer (a):

   ${\text{log}\frac{(4)(2)}{5} = \text{log}\frac{8}{5}}$

2. $\operatorname { log } _ { 2 } M + 2 \operatorname { log } _ { 2 } N$

   Step 1(b):

   ${\text{log}_{2}\textit{M} + \text{log}_{2}\textit{N}^2}$

   Step 2(b):

   ${\text{log}_2(\textit{MN}^2)}$
