Question

question 4
simplify.
-2i (3i)
○ 6i
○ -6i
○ 6
○ -6

Explanation:

Step1: Multiply coefficients and \(i\) terms

Multiply \(-2\) and \(3\), and \(i\) and \(i\): \(-2i(3i)=(-2\times3)(i\times i)\)

Step2: Simplify using \(i^2 = -1\)

Calculate \(-2\times3=-6\) and \(i\times i = i^2=-1\), so \(-6\times(-1)=6\)

Answer:

6 (corresponding to the option "6")
