Step-by-step explanation:

pqr = - 1 × 5 × - 4 = - 5 × - 4 = 20

-5(a - b) = - 5(4 - (- 6)) = -5(4 + 6) = - 5 × 10 = - 50

5s² + st = 5 × (- 3)² + (- 3 × - 7) = (5 × 9) + 21 = 45 + 21 = 66

5c - de = (5 ×- 4) - (5 × - 3) = - 20 - (- 15) = - 20 + 15 = - 5

p² + 3q² = (- 10)² + (3 × (- 2)²) = 100 + (3 × 4) = 100 + 12 = 112

$\frac{mn}{2p}$ = $\frac{(-40)(24)}{2(-3)}$ = $\frac{-960}{-6}$ = 160

$\frac{b^2c}{ad^2}$ = $\frac{(-8)^2(9)}{-3(-2)^2}$ = $\frac{64(9)}{-3(4)}$ = $\frac{576}{-12}$ = - 48
