a ) 5 x 216 x 25 x 4 = 1080 x 100 = 108000
b ) 37 x 16 x 25 x 4 = 592 x 100 = 59200
c ) 36 x ( 28 + 82 ) + 64 x ( 69 + 41 ) = 36 x 110 + 64 x 110 = ( 36 + 64 ) x 110 = 100 x 110 = 11000
d ) 42 x ( 53 + 36 + 11 ) = 42 x 100 = 4200
e) 37 x 45 + 56 x 37 - 37 x 1 = 37 x ( 45 + 56 - 1 ) = 37 x 100 = 3700
h) 17 x 1 + 17 x 81 + 18 x 17 = 17 x ( 1 + 81 + 18 ) = 17 x 100 = 1700
Mik nhanh nhất đấy , nhớ click cho mik nha !!!!!!!!!!!!!!!!!!!
a) 5 x 25 x 216 x 4
= ( 5 x 216 ) x ( 25 x 4 )
= 1080 x 100
= 108000
b) 4 x 37 x 25 x 16
= ( 4 x 25 ) x ( 37 x 16 )
= 100 x 592
= 59200
Lời giải chi tiết:
38 < 83
45 + 23 > 45 – 24
12 + 37 = 37 + 12
56 – 0 = 56 + 0
- 16 + 45 - 37 - 23 - 32
= 29 - 37 - ( - 9 )
= ( - 8 ) - ( - 9 )
= 1
Phần kia bạn tự làm nhé
- 16 + 45 - 37 - 23 + 32 = 1
56 + 35 + 23 + 34 - 18 = 130
mik nha
tks bn nhiều
a) -16 + ( 45 - 37 ) - ( 23 - 32 )
= -16 + 45 - 37 - 23 + 32
= 29 - 28
= 1
b) 56 - ( -35 - 23 ) + ( 34 - 18 )
= 56 + 35 + 23 + 34 - 18
= 91 + 39
= 130

Câu 12 ko chắc!
18 + 45 + 76 + 98 + 34 + 56 + 12 + 37 + 39 + 21 + 87 + 45
= 568
k dùm nha ,mìn kho nhanh nhưng mong bn k mình k lại
HỨA ĐẤY Nguyen Trieu Anh Linh
24 + 56 – 18 = 80 – 18 = 62
82 – 37 + 45 = 45 + 45 = 90
a) 24+56-18=80-18=62
b) 82-37+45=82-82=0
