Answer:

(-2 i) * (-3 i) = -6

Step-by-step explanation:

This is a product between imaginary numbers, so have in mind how the imaginary unit multiplies by itself: [tex]i\,*\,i = i^2=-1[/tex]

So let's work on the product:

[tex]-2\,i\,*\,(-3\,i)= (-2)\,*\,(-3)\,*\,i\,*\,i =(6)\,* i^2\,=(6)\,*\,(-1)= -6[/tex]
