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

k mk nhá

Lời giải chi tiết:

38 < 83

45 + 23 > 45 – 24

12 + 37 = 37 + 12

56 – 0 = 56 + 0

38 < 83

45 + 23 > 45 -24

12 +37 = 37+12

56-0=56+0

Trê 

- 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

<=> 1

56- (-35 -23 ) +(34-18)

=> 56+35+23 +34-18

=> 114 +16=130
