Question

40:{[11+(26-3^3)]*2}

Answer 1

\(=40:\left\{\left[11+\left(26-27\right)\right].2\right\}=40:\left[\left(11-1\right).2\right]=40:20=2\)

Answer 2

\(40:\left\{\left[11+\left(26-3^3\right)\right]\cdot2\right\}\)

\(=40:\left\{\left[11+\left(26-27\right)\right]\cdot2\right\}\)

\(=40:\left\{\left[11+\left(-1\right)\right]\cdot2\right\}\)

\(=40:\left[10\cdot2\right]\)

\(=40:20\)

`=2`

Answer 3

\(40:\left\{\left[11+\left(26-3^3\right)\right].2\right\}\)

\(=40:\left\{\left[11+\left(26-27\right)\right].2\right\}\)

\(=40:\left\{\left[11-1\right].2\right\}\)

\(=40:\left\{10.2\right\}\)

\(=40:20\)

\(=2\)
