Question

T = 160.(2 + 3 + 8 + 7) - (2 + 3 + 8 + 7).60. bằng

Answer 1

`T = 160.(2 + 3 + 8 + 7) - (2 + 3 + 8 + 7).60`

`=  160. 2 + 3 +8+7 - 2 -3-8-7.60`

`= 160. ( 2-2) +(3-3)+(8-8)+(7-7) . 60`

`= 160 . 0 +0+0+0 . 60`

`= 0 . 60`

`=0`

Answer 2

t=160*(2+3+8+7)-(2+3+8+7)*60

t=160*20-20*60

t=3200-1200

t=2000
