Answer 1

_là gì vậy?

Answer 2

136 . 23 + 136 . 17 - 40 . 36

= 136(23 + 17) - 40 . 36

= 136 . 40 - 40 . 36

= 40(136 - 36) = 40 . 100 = 4000

Answer 3

\(136.23+136.17-40.36=136\left(23+17\right)-40.36\)

\(=136.40-40.36=40.\left(136-36\right)\)

\(=40.100=400\)

Answer 4

136 . 23 + 136 . 17 - 40 . 36

= 136(23 + 17) - 40 . 36

= 136 . 40 - 40 . 36

= 40(136 - 36) = 40 . 100 = 4000
