ai đúng  mình sẽ tick cho nhé!   ^_^

Answer 1

\(125+\left\{7,5-\left[8,5:2,5+0,8\right].0,6\right\}-3.6:\left(4-1,5\right)\)

\(=125+\left\{7,5-\left[3,4+0,8\right].0,6\right\}-3,6:2,5\)

\(=125+\left\{7,5-\left[4,2\right].0,6\right\}-1,44\)

\(=125+\left\{3,3.0,6\right\}-1,44\)

\(=125+1,98-1,44\)

\(=126,98-1,44\)

\(=125,54\)

Answer 2

= 125 + { 7.5 - [ 8.5  : 2.5 + 0.8 ] x 0.6 } -3.6 : ( 4 - 1.5 )

= 125 + { 7.5 - ( 3.4 + 0.45 ) 0.9 - 1.5 }

= 125 { 7.5 - 1.53 - 0.9 - 1.5 }

= 125 + { 4.97 - 0.9 - 1.5 }

= 125 + { 4.07 - 1.5 }

= 125 + 2.57 

= 127.57

Tk cho mh nhé , mơn nhìu !!!

Answer 3

= 125 + { 7.5 - [ 8.5  : 2.5 + 0.8 ] x 0.6 } -3.6 : ( 4 - 1.5 )

= 125 + { 7.5 - ( 3.4 + 0.45 ) 0.9 - 1.5 }

= 125 { 7.5 - 1.53 - 0.9 - 1.5 }

= 125 + { 4.97 - 0.9 - 1.5 }

= 125 + { 4.07 - 1.5 }

= 125 + 2.57 

= 127.57
