Question

1, tính

A,1500_{5^3.2^3_11[7^2_5.2^3+8(11^2_121)]}

 

Answer 1

\(1500-\left\{5^3.2^3-11\left[7^2-5.2^3+8\left(11^2-121\right)\right]\right\}\)

\(=1500-\left\{5^3.2^3-11\left[7^2-5.2^3+8.0\right]\right\}\)

\(=1500-\left\{5^3.2^3-11\left[49-5.8+0\right]\right\}\)

\(=1500-\left\{5^3.2^3-11\left[49-40\right]\right\}\)

\(=1500-\left\{5^3.2^3-11.9\right\}\)

\(=1500-\left\{125.8-99\right\}\)

\(=1500-\left\{1000-99\right\}\)

\(=1500-901=599\)

Vậy giá trị biểu thức trên bằng 599
