Найдите значение выражения (xy)^2 при x=12 и y=-0,5; x=-14 и y=-1.

\[\left( \text{xy} \right)^{2}\]

\[x = 12;\ y = - \frac{1}{2}:\]

\[\left( 12 \cdot \left( - \frac{1}{2} \right) \right)^{2} = \left( - \frac{12}{2} \right)^{2} =\]

\[= ( - 6)^{2} = 6^{2} = 36.\]

\[x = - 14;\ y = - 1:\]

\[\left( - 14 \cdot ( - 1) \right)^{2} = 14^{2} = 196.\ \]
