= (4 x 25) x 113 - (5 x 20) x 112

= 100 x 113 - 100 x 112

= 100 x (113 - 112)

= 100 x 1

= 100

4×113×25-5×112×20

=(4×25)×113-(5×20)×112)

=100×113-100×112

=100×(113-112)

=100×1

=100

Trả lời :

25 x 8 x 50 x 125 x 4 x 2

= ( 25 x 4 ) x ( 8 x 125 ) x ( 50 x 2 )

= 100 x 1000 x 100

= 100 000 000

30000000 nha minh ban k cho mik mik se tra lai

\(35600:25:4\)
\(=35600:\left(25\times4\right)\)
\(=35600:100\)
\(=356\)

35600 : 25 : 4

= 35600 : ( 25 x 4 )

=  35600 : 100

Yêu cầu là gì bạn???

tính bằng cách thuận tiện nhất ạ 

48 x 125 + 875 x 49 

48 x 49 x ( 125 + 875 ) 

48 x 49 x 1000

2352 x 1000

2352000

K nha

48 x 125 + 875 x 49

= 48 x 125 + 125 x 7 x 49

= 48 x 125 + 125 x 343

= (48 + 343) x 125

= 391 x 125

= 48875

Hello bạn hồng Ngọc trang

1. 

= 10 000 - 29 x 11

= 10 000 - 319

= 9681

2.

= ( 3/7 + 4/7 ) + ( 4/9 + 5/9 )

= 1 + 1

= 2
