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

`(mn)/(2p)` =
`((-40)(24))/(2(-3))` =
`(-960)/(-6)` = 160

`(b^2c)/(ad^2)` =
`((-8)^2(9))/(-3(-2)^2)` =
`(64(9))/(-3(4))` =
`(576)/(-12)` = - 48
