hok tốt 

567 + 567 . 101 - 567 - 567

= 567 ( 101 - 1 )

= 567 . 100

= 56700 nhé bạn

Giúp dùm vs ạ

567 x 34 + 567 x 67 x 567 - 567

= 567 x 34 + 567 x 37989  - 567

= 567 x ( 34 + 37989 ) - 567

= 567 x 38023 - 567

= 21559041 - 567

= 2558474

\(567\times34+567\times67-567\)

\(=567\times34+567\times67-567\times1\)

\(=567\left(34+67-1\right)\)

\(=567\times100=56700\)

=0 k nha

N=0 nha

\(-567-\left(-113\right)+\left(-69\right)-\left(113-567\right)\)

\(=-567+113+\left(-69\right)-113+567\)

\(=\left(-567+567\right)+\left(113-113\right)+\left(-69\right)\)

\(=\left(-69\right)\)

\(-567-\left(-113\right)+\left(-69\right)-\left(113-567\right)\)

\(=-567+113-69-113+567\)

\(=\left(-567+567\right)+\left(113-113\right)-69\)

\(=0+0-69=-69\)

-7 + 2x = -37 - (-26)

\(\frac{1234\times567-667}{567+1234\times566}=\frac{1234\times\left(566+1\right)-667}{567+1234\times566}=\frac{1234\times566+1234-667}{567+1234\times566}\)

\(=\frac{1234\times566+567}{567+1234\times566}=1\)
