sorry nha,mk ko giải ra đc

bn thông cảm

\(a,\left(5318-46+151\right)-\left(318-146+51\right)\)

a) Tìm các số nguyên x thỏa mãn: \(-7< x< 8.\)

\(x=\left\{-6;-5;-4;-3;-2;-1;0;1;2;3;4;5;6;7\right\}.\)

b)  Tính nhanh các tổng:

1)  \(631+\left[587-\left(287+231\right)\right]=631+587-287-231=\left(631-231\right)+\left(587-287\right)=400+300=700.\)

2)  \(\left(-524\right)-\left[\left(476+246\right)-45\right]=\left(-524-246\right)+\left(-476+45\right)=-1201.\)

= 0 đó k cho mk

Kết quả của phép tính trên là : 523

Chúc bn hl tốt !

Hải tiểu mi sai đó các bạn thử lại đi
