Multiply and simplify the product. 2i(4 - 5i). Select the product.
-2i, 2i, -10 + 8i, 10 + 8i

Solution:

We will make use of the concept of multiplying Complex Numbers to find the product.

The product of 2i and (4 - 5i) is calculated as follows:

= 2i(4 + 5i)

= 8i + 2i × (5i)

= 8i + 10i²

Therefore i² = -1

 8i +10(-1)

= 8i -10

Thus, 2i (4 – 5i) = -10 + 8i

Multiply and simplify the product. 2i(4 - 5i). Select the product.

Summary:

The product. 2i(4 - 5i) is -10 + 8i
