Question

simplify.
5\cdot3i
write your answer in the form a + bi.

Explanation:

Step1: Identify the form

The complex number form is \(a + bi\), where \(a\) is the real part and \(b\) is the coefficient of the imaginary unit \(i\).

Step2: Analyze the given number

The given number is \(5.3i\). Here, the real part \(a = 0\) (since there's no real number term) and the coefficient of \(i\) (the imaginary part coefficient \(b\)) is \(5.3\). So we can write it as \(0 + 5.3i\).

Answer:

\(0 + 5.3i\)
