\[\boxed{\text{6.184.}}\]

\[\textbf{а)}\ 6^{2} + 2^{2} = 36 + 4 = 40;\ \]

\[40 + 50 = 90;\ \]

\[90\ :15 = 6;\ \]

\[6 \cdot 20 = 120;\ \]

\[120 - 25 = 95.\ \]

\[\textbf{б)}\ 3^{3} + 5^{2} = 27 + 25 = 52;\ \]

\[52\ :13 = 4;\ \]

\[4 \cdot 25 = 100;\ \]

\[100 + 150 = 250;\ \]

\[250\ :125 = 2.\ \]

\[\textbf{в)}\ 4^{3} - 3^{2} = 64 - 9 = 55;\ \]

\[55\ :11 = 5;\ \]

\[5 \cdot 40 = 200;\ \]

\[200 - 75 = 125;\ \]

\[125\ :25 = 5.\ \]

\[\textbf{г)}\ 2^{3} + 9^{2} = 8 + 81 = 89;\ \]

\[89 + 21 = 110;\ \]

\[110\ :11 = 10;\ \]

\[10 \cdot 18 = 180;\ \]

\[180\ :45 = 4.\ \ \ \]
