The value of the expression is 29

How to evaluate the expression?

The expression is given as

(2 - 5i)(p + q)

Where

p = 2

q = 5i

Substitute these values in (2 - 5i)(p + q)

So, we have

(2 - 5i)(p + q) = (2 - 5i)(2 + 5i)

Apply the difference of two squares

(2 - 5i)(p + q) = 4 - (-25)

Evaluate the difference

(2 - 5i)(p + q) = 29

Hence, the value of the expression is 29
