k mk nha 

thank you

725 : 25 + 525 : 25

= ( 725 + 525 ) : 25

= 1250 : 25

= 50

k mk nha

Mk cảm ơn bạn nhiều

Thank you so much !

(72 x 135 + 9 x 28 x 15) : 25 - 3500 : 25

= [72 x 135 + 28 (9 x 15)] : 25 - 3500 : 25

= (72 x 135 + 28 x 135) : 25 - 3500 : 25

= [135 x (72 + 28)] : 25 - 3500 : 25

= [135 x 100] : 25 - 3500 : 25

= 13500 : 25 - 3500 : 25

= (13500 - 3500) : 25

= 10000 : 25

= 400

????? buff à , mà nhanh v 

25x1357x4

=1357x(25x4)

=1357x100

=135 700

giui giup toi nha 

82,5:25:4

=82,5 : (25x4)

=82,5 : 100

=0,825

82,5:25:4

= 82,5 : ( 25 x 4 )

= 82,5 : 100

= 0,825

# HOK TỐT #

a) 25 + 69 + 75 + 11

= (25 + 75) + (69 + 11)

= 100 + 80

= 180

b) 64 x 867 + 36 x 867

= (64 + 36) x 867 

= 100 x 867

= 86700

c) 25 x 989 x 4 + 25

= 25 x 4 x 989 + 25

= 100 x 989 + 25

= 98900 + 25

= 98925

a)25 + 69 + 75 + 11 

=(25 + 75) + (69 + 11)

=100 + 80

=180

b)64 * 867 + 36 * 867

=(64 + 36) * 867

=100 * 867

=86700

c)25 * 989 * 4 +25

=25*3956+25

=25*(3956+1)

=25*3957

=98925

Ta có : 234.25.3.4=(234.3).(25.4)=702.100=70200

234*25*3*4

=(234*3)*(25*4)

=702*100

=70200
