136 . ( 668 - 588 ) - 404 . 25 = 780
\(136\cdot\left(668-588\right)-404\cdot25\)
\(=136\cdot80-404\cdot25\)
\(=10880-10100\)
\(=780\)
136 . ( 688 - 588 ) - 404 . 25
= 136 . 100 - 10100
= 13600 - 10100
= 3500
136 . ( 668 - 588 ) - 404 . 25
= 136 . 80 - 10100
= 10880 - 10100
= 780
xin lỗi , mình nhầm
136 . ( 668 - 588 ) - 404 . 25
= 136 . 80 - 404 . 25
= 10880 - 10100
= 780
