(2^3 -125)-(1997-125+26)=(8-125)-(1997-125+26)=8-125-1997+125-26=(125-125)+8-1997-26=0+8-1997-26=-2015

-2015 nha tich minh

(2^​3 - 125) - (1997 - 125 + 26) = (125 - 125) - 1898 = 0 - 1898 = -1898

5^50.5+125=5^50.5+5^3=5^50.5+5^2.5=5.[5^50+5^2]                       

Rồi tự làm tiếp nha bạn

Bổ sung bài : Tính

\(5^{25}.5.5^{25}+\left|-125\right|\)

\(=5^{51}+125\)

Kết quả chỉ dừng ở đó vì không thể tính ra con số cụ thể được nữa.

    5^25..5:5^25+/-125/

26.(-125) – 125.(-36)

các bạn cho mk vài li-ke cho tròn 980 với 

26.(-125)-125.(-36)

= -26 . 125 - 125 . -36

= 125 . ( -26+36)
