=128 - [68+8.4]:4
= 128 - 100:4
= 128 - 25
= 103
128 - [68 + 8(37 - 35)2 ] : 4
= 128 - [68 + 8.22 ] : 4
= 128 - [68 + 32] : 4
= 128 - 100 : 4
= 128 - 25
= 103
\(128-\left[68+8.\left(37-35\right)^2\right]:4\)
\(=128.\left[68+8.4\right]:4\)
\(=128.100:4\)
\(=32025\)
128 - [68 + 8(37 - 35)2 ] : 4
= 128 - [68 + 8.22 ] : 4
= 128 - [68 + 32] : 4

= 128 - 25
= 103
hok tốt
\(128-\left[68+8\left(37-35\right)^2\right]:4\)
=\(128-\left[68+8.2^2\right]:4\)
=\(128-\left[68+8.4\right]:4\)
= \(128-\left[68+32\right]:4\)
= \(128-100:4\)
= \(128-25\)
= \(103\)
Chúc bạn học tốt !!!
