35x34+35x34+65x75+65x45
= (35 x 34 + 35 x 34) + (65 x 75 + 65 x 45)
= 35 x 34 x 2 + 65 x (75 + 45)
= 2380 + 65 x 120
= 2380 + 7800
= 10180
35x34+35x34+65x75+65x45
= (35 x 34 + 35 x 34) + (65 x 75 + 65 x 45)
= 35 x 34 x 2 + 65 x (75 + 45)
= 2380 + 65 x 120
= 2380 + 7800
= 10180
a) 34 x 35 + 86 x 35 + 65 x 75 + 65 x 45
= ( 34 + 86 ) x 35 + 65 x ( 75 + 45 )
= 120 x 35 + 65 x 120
= 120 x ( 65 + 35 )
= 120 x 100
= 12000
b) ............
a, 35.(34+86) +65.(75+45)= 35. 120 +65.120= 120.(35+65)=120.100=12000
a. (286 : 11 +7 x 2) x 3 - 13
= (26 + 14) x 3 - 13
= 40 x 3 - 13
= 120 - 13
= 107
b. 35 x 34 + 65 x 75 + 35 x 38 + 65 x 45
= (35 x 34) + (65 x 75) + (35 x 38) + (65 x 45)
= 1190 + 4875 + 1330 + 2925
= (1190 + 1330) + (4875 + 2925)
= 2520 + 7800
= 10 320

đúng 100%
=65*(75+10+15)
=65*100
=6500
=6500 tick tớ nhé Minions
