\(2029-\left\{\left[39-\left(2^3.3-21\right)^2:3+2018^0\right]\right\}\)
\(=2029-\left\{\left[39-\left(8.3-21\right)^2:3+2018^0\right]\right\}\)
\(=2029-\left\{\left[39-\left(24-21\right)^2:3+2018^0\right]\right\}\)
\(=2029-\left\{\left[39-3^2:3+2018^0\right]\right\}\)
\(=2029-\left\{\left[39-9:3+1\right]\right\}\)
\(=2029-\left\{\left[39-3+1\right]\right\}\)
\(=2029-37\)
\(=2022\)
