Объяснение:

$\frac{5.3 \times {8.2}^{2} - 5.3 \times 1.8 {}^{2} }{10.6 \times 6.6 {}^{2} - 10.6 \times 3.4 {}^{2} } = \frac{5.3( {8.2}^{2} - {1.8}^{2} )}{10.6( {6.6}^{2} - {3.4}^{2} ) } = \frac{5.3 ({8.2} - {1.8})(8.2 + 1.8)}{10.6 ({6.6}- {3.4})(6.6 + 3.4)} = \frac{6.4 \times 10}{2 \times 3.2 \times 10} = \frac{2}{2} = 1$
