Question

simplify the expression: 2(1 + j) =

Explanation:

Step1: Apply distributive property

Use the distributive property \(a(b + c)=ab+ac\), here \(a = 2\), \(b=1\), \(c = j\). So \(2(1 + j)=2\times1+2\times j\).

Step2: Calculate each term

\(2\times1 = 2\) and \(2\times j=2j\). Then combine them: \(2 + 2j\).

Answer:

\(2 + 2j\)
