I think it’s b I’m not sure
The multiplication of the expressions 2i and (4 – 5i) is 10 + 8i. Then the correct option is D.
<h3>What is multiplication?</h3>
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expressions are 2i and (4 – 5i).
Then the product of the expression will be given as
2i (4 – 5i)
8i – 10i²
And we know that i² = -1
Then we have
8i – 10 (–1)
10 + 8i
