Question

The equation: -2(4-5i)=-8+10i demonstrates which of the following properties?-commutative property-distributive property-associative property -identity property

Answer 1

Given expression

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

So,

$\begin{gathered} -2(4-5i)=-2(4)-2(-5i) \\ =-8+10i \end{gathered}$

Hence, this is the distributive law.
