Answer 1

Đáp án:

B=15+17+19+...+155B=15+17+19+...+155

 Phép tính B có số số hạng là:

   (155−15):2+1=71(155-15):2+1=71 (số hạng)

Tổng phép tính B là:

   (155+15).71:2=6035(155+15).71:2=6035

C=4.325.6+4.69.24+3.399.8C=4.325.6+4.69.24+3.399.8

C=(4.6).325+276.24+(3.8).399C=(4.6).325+276.24+(3.8).399

C=24.325+276.24+24.399C=24.325+276.24+24.399

C=24.(325+276+399)C=24.(325+276+399)

C=24.1000C=24.1000

C=24000C=24000

`D = 43 . 37 + 43 . 73 + 57 . 66 + 57 .  44`

D=43.(37+ 73)+57.(66+44)D=43.(37+ 73)+57.(66+44)

D=43.110+57.110D=43.110+57.110

D=(43+57).110D=(43+57).110

D=100.110D=100.110

D=11000D=11000

E=48.19+48.115+134.52E=48.19+48.115+134.52

E=48.(19+115)+134.52E=48.(19+115)+134.52

E=48.134+134.52E=48.134+134.52

E=134.(48+52)E=134.(48+52)

E=134.100E=134.100

E=13400

Answer 2

A=15+17+19+...+155B=15+17+19+...+155

 Phép tính B có số số hạng là:

   (155−15):2+1=71(155-15):2+1=71 (số hạng)

Tổng phép tính B là:

   (155+15).71:2=6035(155+15).71:2=6035

B=4.325.6+4.69.24+3.399.8C=4.325.6+4.69.24+3.399.8

B=(4.6).325+276.24+(3.8).399C=(4.6).325+276.24+(3.8).399

B=24.325+276.24+24.399C=24.325+276.24+24.399BB=

B=24.(325+276+399)C=24.(325+276+399)

B=24.1000C=24.1000

B=24000C=24

D=43.1+E

C=48.(19+115)+134.52E=48.(19+115)+134.52

C=48.134+134.52E=48.134+134.52

C=134.(48+52)E=134.(48+52)

C=134.100E=134.100

C=13400
