Answer 1

Explicación paso a paso:

i) a = -2, b = -3, c = -1

ii) a = 3, b = 2, c = -4

• a × (b - c) • b × (c + a) • a×c×(-1)

= 3×(2-(-4)) = 2×(-4+3) = 3×(-4)×(-1)

= 3×(2+4) = 2×(-1) = 3×4

= 18 = -2 = 12

iii) a = 3, b = -1, c = -5

• a × (b - c) • b × (c + a) • a×c×(-1)

= 3×((-1)-(-5)) = (-1)×(-5+3) = 3×(-5)×(-1)

= 3×(-1+5) = (-1)×(-2) = 3×5

= 3×(4) = 2 = 15

= 12
