\(2011+5\left[300-\left(17-7^2\right)\right]\)

\(=2011+5\left[300-\left(17-49\right)\right]\)

\(=2011+5\left[300-\left(-32\right)\right]\)

\(=2011+5.332\)

\(=2011+1660\)

\(=3671\)

\(50-\left[\left(50-2^3.5\right):2+3\right]\)

\(=50-\left[\left(50-8.5\right):2+3\right]\)

\(=50-\left[10:2+3\right]\)

\(=50-8\)

\(=42\)

\(2^4-50:25+13.7\)

\(=16-50:25+13.7\)

\(=16-2+91\)

\(=14+91\)

\(=105\)

\(1+1=2\)
