Question

jika a=-4 b=3 c=-2 d =1 nilai dari ab+ bc -cd -abcd​

Answer 1

Verified answer

= ab + bc - cd - abcd

= (-4)(3) + (3)(-2) - (-2)(1) - (-4)(3)(-2)(1)

= -12 - 6 + 2 - 24

= -18 + 2 - 24

= -16 - 24

= -40

Answer 2

ʎɐp ǝɔᴉu ɐ ǝʌɐɥ :>

a = - 4

b = 3

c = - 2

d = 1

ab + bc - cd - abcd

= (-4 × 3) + (3 × - 2) - (-2 × 1) - (-4 × 3 × - 2 × 1)

= - 12 + (-6) - (-2) - 24

= - 12 - 6 + 2 - 24

= - (12 + 6) + 2 - 24

= - 18 + 2 - 24

= - 16 - 24

=> - 40
