(A) 34
(B) 34-30i
(C) 0-16i
(D) None of the above

Answer 1

To find the product of complex numbers (-3-5i)(-3+5), multiply the real parts and the imaginary parts separately. The correct answer is -16.

Step-by-step explanation:

To find the product of (-3-5i)(-3+5), we can use the distributive property. When multiplying two complex numbers, we multiply the real parts and the imaginary parts separately.

In this case, (-3-5i)(-3+5) becomes (9-15i+15i-25), which simplifies to (9-25).

The final answer is -16. So the correct option is (C) 0-16i.
