Question

Simplify the expression below as much as possible.(6 - 4i ) + (-3 + 4i ) - (2 - 8i )A.1 - 8iB.1 + 8iC.5 - 8iD.5 + 8i

Answer 1

Given the expression below

`\left(6-4i\right)+(-3+4i)-(2-8i)`

Simplifying the expression gives,

`\begin{gathered} =6-4i-3+4i-2+8i \\ Collect\text{ like terms} \\ =6-3-2-4i+4i+8i \\ =1+8i \end{gathered}`

Hence, the answer is 1 + 8i (option B)
