  1. [36.4-4.(82 – 7.11)²]: 4-2022^0
    =[36.4-4.(82-77)²]:4-2022^0
    =[36.4-4.     5²    ]:4-2022^0
    =[36.4-4.    25     ]:4-2022^0
    =[144 –    100      ]:4-2022^0
    =        44              :4-2022^0
    =                  11       -2022^0
    =                  11       –      1
    =                        10

  2. $\text{[ 36 . 4 – 4 . ( 82 – 7 . 11 )² ] : 4 -}$ $2022^0$
    $\text{= [ 36 . 4 – 4 . ( 82 – 7 . 11 )² ] : 4 – 1}$
    $\text{= [ 36 . 4 – 4 . ( 82 – 77 )² ] : 4 – 1}$
    $\text{= [ 36 . 4 – 4 . 5²] : 4 – 1}$
    $\text{= [ 36. 4 – 4 . 25 ] : 4 – 1}$
    $\text{= [ 144 – 100 ] : 4 – 1}$
    $\text{= 44 : 4 – 1}$
    $\text{= 11 – 1}$
    $\text{= 10}$
    $\text{#Pánh#}$
