  1. $\text{a) 168+79+132}$
    $\text{=(168+132)+79}$
    $\text{=300+79}$
    $\text{=379}$
    $\text{b) }$$5^{9}:$ $5^{7}+12.3+$ $7^{0}$
    $\text{=}$$5^{9-7}+36+1$
    $\text{=}$$5^{2}+36+1$
    $\text{=25+36+1}$
    $\text{=62}$
    $\text{#mct}$

  2. 168+79+132
    =(168+132)+79
    =300+79
    =379
    ———
    5^9 :5^7+12.3+7^0
    =5^2+(36+1)
    =25+37
    =62
