Question

Помогите плзз только 504

Answer 1

$\: 3 \times ( - 5) {}^{2} = 3 \times 25 = 75 \\ - 4 \times ( - 5) {}^{3} = - 4 \times (- 125) = 500$
$- \frac{1}{4} \times ( - 2) {}^{6} = - \frac{1}{4} \times 64 = - \frac{64}{4} = - 16 \\ - 3 \times ( \frac{1}{3}) {}^{3} = - 3 \times \frac{1}{27} = - \frac{3}{27} = - \frac{1}{9}$
${2}^{3} + {3}^{2} = 8 + 9 = 17 \\ {7}^{2} - {5}^{2} = 49 - 25 = 24$
