Question

use the imaginary number i to rewrite the expression below as a complex number. simplify all radicals. 3 + √-1

Explanation:

Step1: Recall the definition of \(i\)

The imaginary unit \(i\) is defined as \(i = \sqrt{-1}\).

Step2: Substitute \(i\) into the expression

Given the expression \(3+\sqrt{-1}\), substitute \(\sqrt{-1}\) with \(i\). So the expression becomes \(3 + i\).

Answer:

\(3 + i\)
