Còn tùy vào điểm thi bạn nhé.

A= \(\dfrac{25}{18}-\dfrac{25}{21}+\dfrac{25}{21}-\dfrac{25}{24}+...+\dfrac{25}{123}-\dfrac{25}{126}\)

A= \(\dfrac{25}{18}-\dfrac{25}{126}\)

A= \(\dfrac{25}{21}\)

Hoặc ngay dòng 2 bạn làm như thế này cũng được: \(25.\left(\dfrac{1}{18}-\dfrac{1}{21}+...+\dfrac{1}{123}-\dfrac{1}{126}\right)\)

|a²+5²|=(-43)+|-93|

=> a²+25=(-43)+93

=> a²+25=50

=> a²=50-25

=> a²=25

=> a=5 hoặc a=-5

Vì đề yêu cầu tìm số nguyên âm a nên a=-5

Vậy a=-5
