Answer 2

Resposta:

7*68

7*(60+8)

7*60=420

7*8=56

420+56= 476

35*9

9*(30+5)

9*30= 270 9*5=45

270+45= 315

71*24

70*(20+4)

70*20=1400 70*4=280

1400+ 280= 1680+1*24=1704

42*57

40*(50+7)

40*50=2000

40*7=280

2280+2*57=114+2280=2394

136*402

136*(400+2)

136*4*100 = 136*400

136*4*100=400+120+24*100

544*100=54400

136*2= 200+60+12 = 272

54400+272=54672

espero ter ajudado!
