\[\textbf{а)}\ 2^{3} = 8;\ \ 3^{2} = 9 \Longrightarrow\]
\[\Longrightarrow 3^{2} > 2^{3}\ на\ 1.\]
\[\textbf{б)}\ 5^{2} = 25;\ \ 2^{5} = 32 \Longrightarrow\]
\[\Longrightarrow 2^{5} > 5^{2}\ на\ 7.\]
\[\textbf{в)}\ 2 \cdot 3^{2} = 2 \cdot 9 = 18;\ \ \ 3 \cdot 2^{3} =\]
\[= 3 \cdot 8 = 24 \Longrightarrow\]
\[\Longrightarrow 3 \cdot 2^{3} > 2 \cdot 3^{2}\text{\ \ }на\ 6.\]
\[\textbf{г)}\ (11 + 19)^{2} = 30^{2} = 900;\ \ \]
\[11^{2} + 19^{2} = 121 + 361 = 482\]
