  1. $\text{[ 157. $1^{2021}$ – $( 13 – 4 )^{2}$ ] : 4 – $3^{5}$ : $3^{2}$}$
    $\text{= [ 157. 1 – 9² ] : 4 – 3³}$
    $\text{= ( 157 – 81 ) : 4 – 27}$
    $\text{= 76 : 4 – 27}$
    $\text{= 19 – 27}$
    $\text{= -8}$

  2. Ko chép lại đề nha!!!
    = (157.1 – $9^{2}$) : 4 – $3^{3}$ 
    = (157 – 81) : 4 – 27
    = 76 : 4 – 27
    = 19 – 27
    = -8
