Question

6. Calculează după model: 34 x 11 = 34 x (10 + 1) = 34 x 10 + 34 x 1 = 340 + 34 = 374 25 x 11 = 26 x 11 = 35 x 11 = 81 x 11 = 72 x 11 = 32 x 11 = 63 x 11 = 54 x 11 = Va rog REPEDE dau COROANA si inima​

Answer 1

Răspuns:

25·11=25·(10+1)=25·10+25·1=250+25=275

26·11=26·(10+1)=26·10+26·1=260+26=286

35·11=35·(10+1)=35·10+35·1=350+35=385

81·11=81·(10+1)=81·10+81·1=810+81=891

72·11=72·(10+1)=72·10+72·1=720+72=792

32·11=32·(10+1)=32·10+32·1=320+32=352

54·11=54·(10+1)=54·10+54·1=540+54=594

Answer 2

25×11 =25×(10+1)=25×10+25×1= 250+25=275
26×11=26×(10+1)= 26×10+26×1=260+26=286
35×11=35×(10+1)=35×10+35×1=350+35=385
81×11=81×(10+1)=81×10+81×1=810+81=891
72×11=72×(10+1)=72×10+72×1=720+72=792
32×11=32×(10+1)=32×10+32×1=320+32=352
63×11=63×(10+1)=63×10+63×1=630+63=693
54×11=54×(10+1)=54×10+54×1=540+54=594
