tk mk nha....

151956 : 189 =  804

56 x \((4575+396)\)= 56 x 4971

                                     = 278376

69230 - 17045 : 35 x 27 = 69230 - \((17045:35\cdot27)\)

                                   = 69230 - 13149

                                   = 56081

Tự tính cuối cùng nha

151956 : 189 = 804

56 x ( 4575 + 396 ) = 56 x 4971  = 278376

69230 - 17045 : 35 x 27 = 69230 - 487 x 27 = 69230 - 13149 = 56081

528 x 132 + 96096 : 66 = 69696 + 1456 = 71152

a) 56 x 147- 56 x 47 = 56 x(147- 47) + 134

                                 =56 x 100 +134

                                 =5734          

\(56.147-56.47+134=56.\left(147-47\right)+134=56.100+134=5600+134=5734\)

Thanks mấy bn trl giúp mik nha

9072 - 56 x 7 + 56 x 70 + 56 x 23

= 9072 - 56 x ( 7 + 70 + 23 )

= 9072 - 56 x 100

= 9072 - 5600

= 3472

ôi trời ơi câu này khó quá không làm nổi

( 56 x 27 + 56 x 35 ) : 62

= 56 x ( 27 + 35 ) : 62

= 56 x 62 : 62

= 56 x 1

= 56

 ~ Ai tk mk mk tk lại nha ~

( 56 x 27 + 56 x 35 ) : 62 

= 56 x ( 27 + 35 ) : 62 

= 56 x 62 : 62 

= 56

( 56 x 27 + 56 x 35) : 62 = 56 x ( 27+35) : 62 = 56 x 62 : 62 = 56

= -56 - 3425353 + 23 + 56 + 3425353 - 23

- 56 - 3 425 353 + 23 + ( 56 + 3 425 353 - 23 )

= ( 56 - 56 ) - ( 3 425 353 - 3 425 353 ) + ( 23 - 23 )

= 0 - 0 + 0 = 0

1 2 + − 1 2 + − 2 3 + 2 3 + 3 4 + − 3 4 + − 4 5 + 4 5 + 5 6 + − 5 6 = 0

Đây nha

hok tốt nhé!

   64 x 56 + 81 x 44 + 17 x 56

= 56 x ( 64 + 17 ) + 81 x 44

= 56 x 81 + 81 x 44
