Question

simplify.
9i + 5i
write your answer in the form a + bi.

Explanation:

Step1: Identify like terms

The expression is \(9i + 5i\). Both terms have the imaginary unit \(i\), so they are like terms.

Step2: Combine like terms

To combine them, we add the coefficients: \(9 + 5 = 14\). So \(9i + 5i = 14i\). In the form \(a + bi\), \(a = 0\) and \(b = 14\), so it is \(0 + 14i\).

Answer:

\(0 + 14i\)
