Question

{210:[16+3.(6+3. 2 mũ 2)]}

Answer 1

\(\left\{210:\left[16+3\cdot\left(6+3\cdot2^2\right)\right]\right\}\)

\(=210:\left[16+3\cdot\left(6+3\cdot4\right)\right]\)

\(=210:\left[16+3\cdot\left(6+12\right)\right]\)

\(=210:\left(16+3\cdot18\right)\)

\(=210:\left(16+54\right)\)

\(=210:70\)

\(=3\)
