Question

Evaluate (2 minus 5 i) (p + q) (i) when p = 2 and q = 5 i.

Answer 1

Answer:

$29i$

Step-by-step explanation:

From this information, we can write the following equation: $(2-5i)(2 + 5i)(i)$

We can see that there is the factorization of the difference of squares, so we can first expand that. The equation will become the following: $(4+25)(i)$

= $29i$
