Question

375:{32-[4+(5.3 mũ 2-42)]}

Answer 1

\(375:\left\{32-\left[4+\left(5.3^2-42\right)\right]\right\}\)

\(=375:\left\{32-\left[4+\left(45-42\right)\right]\right\}=375:\left\{32-\left[4+3\right]\right\}=375:\left\{32-7\right\}\)

=\(375:25=15\)

Answer 2

\(375:\left\{32-\left[4+\left(5.3^2-42\right)\right]\right\}\)

\(=375:\left\{32-\left[4+\left(45-42\right)\right]\right\}\)

\(=375:\left\{32-\left[4+3\right]\right\}\)

\(=375:\left\{32-7\right\}\)

\(=375:25\)

\(=15\)
