Question

Помогите плзз только 504

Answer 1

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