Question

Subtract (5 – 2i) – (1 + 8i). Which property allows you to write the expression as 5 – 2i – 1 – 8i?
associative
commutative
distributive
identity

Answer 1

distributive is the answer 

Answer 2

Answer:

The correct option is 3, i.e., Distributive property.

Step-by-step explanation:

Distributive property: If a, b and c are real three numbers, then

$a(b+c)=a(b)+a(c)=ab+ac$

The given expression is

$(5-2i)-(1+8i)$

Using distributive property in can be rewritten as

$5-2i-(1)-(8i)$

$5-2i-1-8i$

It means distributive property allows as to write the expression (5 – 2i) – (1 + 8i) as 5 – 2i – 1 – 8i.

Therefore, the correct option is 3.
