Ответ:
\[\frac{324^{2} - 224^{2}}{200 \cdot 1096} =\]
\[= \frac{(324 - 224)(324 + 224)}{200 \cdot 1096} =\]
\[= \frac{100 \cdot 548}{200 \cdot 1096} = \frac{1}{4} = 0,25.\]
\[\frac{324^{2} - 224^{2}}{200 \cdot 1096} =\]
\[= \frac{(324 - 224)(324 + 224)}{200 \cdot 1096} =\]
\[= \frac{100 \cdot 548}{200 \cdot 1096} = \frac{1}{4} = 0,25.\]
