Answer:
7+22i
Step-by-step explanation:
Since this is like a binomial, you have to apply the foil method
(-2+3i)(4-5i)=-8+10i+12i+15
(the 15 is the product of 3i*-5i)
Now, you combine like terms
-8+15=7
10i+12i=22i
so the expression in a+bi form is 7+22i
I got 2.935483 so you might be able to round to 3.
7x10x2 basically the opposite the expression
