Answer 1

[Nguyễn Thảo Nguyên]

c) 6 . 47 . 8 – 12 . 34 . 4 + 24 . 87 . 2
= 2256 - 1632 + 4176
= 4800

d) 11. 74 + 22. 13
= 814 + 286
= 1100

e) 36 . 24 + 12. 28
= 864 + 336
= 1200

g) 3737 . 41 – 4141 . 37
= 153217 - 153217
= 0

h) 35 . 12 + 65 . 13
= 420 + 845
= 1265

h) 35 . 12 + 65 . 13

g) 3737 . 41 – 4141 . 37

h) 35 . 12 + 65 . 13

Answer 2

[Lương Thị Vân Anh]

c) 6 . 47 . 8 - 12 . 34 . 4 + 24 . 87 . 2

= 48 . 47 - 48 . 34 + 48 . 87

= 48 ( 47 - 34 + 87 )

= 48 . 100

= 4800

d) 11 . 47 + 22 . 13

= 11 . 47 + 11 . 2 . 13

= 11 ( 47 + 26 )

= 11 . 73

= 803

e) 36 . 24 + 12 . 28

= 36 . 24 + 12 . 2 . 28

= 36 . 24 + 24 . 28

= 24 ( 36 + 28 )

= 24 . 64

= 1536

f) ( 2 + 4 + 6 + ... + 100 ) . ( 36 . 333 - 108 . 111 )

= ( 2 + 4 + 6 + ... + 100 ) . 0

= 0

g) 3737 . 41 - 4141 . 37

= 37 . 101 . 41 - 41 . 101 . 37

= 0

h) 35 . 12 + 65 . 13

= 35 . 12 + 65 . 12 + 65

= 65 ( 35 + 65 + 1 )

= 65  . 101

= 6565
