Hướng dẫn giải
Đáp án đúng là: D
\(125 \cdot {2^3} - 5\left\{ {\left[ {8,51 + 4 \cdot {{\left( {\frac{3}{4} - \frac{2}{5}} \right)}^2}} \right] + {1^{2022}}} \right\}\)
\( = 125 \cdot 8 - 5\left\{ {\left[ {8,51 + 4 \cdot {{\left( {\frac{7}{{20}}} \right)}^2}} \right] + 1} \right\}\)
\( = 1000 - 5\left\{ {\left[ {8,51 + 4 \cdot \frac{{49}}{{400}}} \right] + 1} \right\}\)
\( = 1000 - 5\left\{ {\left[ {8,51 + \frac{{49}}{{100}}} \right] + 1} \right\}\)
\( = 1000 - 5\left\{ {\left[ {8,51 + 0,49} \right] + 1} \right\}\)
\( = 1000 - 5\left\{ {9 + 1} \right\}\)
\( = 1000 - 50\)
= 950
