Answer 1

Explicación paso a paso:

Si:

a = 1, b = 2, c = 3, d = 4, m = ½, n = ⅔, p = ¼

a) (4m + 8p)•(a² + b²)•(6n - d)

= (4•½ + 8•¼)•(1² + 2²)•(6•⅔ - 4)

= (4/2 + 8/4)•(1•1 + 2•2)•(12/3 - 4)

= (2 + 2)(1 + 4)(4 - 4)

= 4 × 5 × 0

= 0

b) (c - b)•(d - c)•(b - a)•(m - p)

= (3 - 2)•(4 - 3)•(2 - 1)•(½ - ¼)

= 1 × 1 × 1 × ¼

= ¼ = 0,25
