57 x 76 + 13 x 57 + 11 x 57

= 57 x ( 76 + 11 + 13 )

= 57 x 100

= 5700

57 x 76 + 13 x 57 + 11 x 57

=  57 ( 76 + 13 + 11 )

= 57 x 100

= 5700

57x76+13x57+11x57

X/36 = 76/57

=> X = 36x76/57

=> X = 48

x ko tồn tại

48/36

`x/36=76/57`

`57xx x=76xx36`

`57 xx x=2736`

`x=2736:57`

`x=48`

\(x=\dfrac{76}{57}\times36=48\)

\(\dfrac{x}{36}=\dfrac{76}{57}\)

\(\dfrac{x}{36}=\dfrac{4}{3}\)

\(\dfrac{x}{36}=\dfrac{48}{36}\)

\(\Rightarrow x=48\)

tick mik nha 

Kết quả phép tính trên là:

57 x 76 + 147 - 43 x 71 = 1426

Đáp số: 1426

57 x 76 + 147 - 43 x 71

=4332+147-3053

=4479-3053

=1426

Vậy...

57 x 76 + 147 - 43 x 71

= ( 57 x 76 ) + 147 - ( 43 x 71 )

= 4332 + 147 - 3053

= ( 4332 + 147 ) - 3053

= 4479 - 3053

= 1426

4332 + 6321 - 3053

= 10653 - 3053

= 7600

ủng hộ nha bn!

57 x 76 + 43 x 147 - 43 x 71

=57x76+43.(147-71)

=57x76+43x76

=(57+43)x76=100x76=7600

57 x 76 + 43 x 147 - 43 x 71 

= 4332 + 6321 - 3053

= 10653 - 3053

= 7600
