Q:

Jamal is doing electronics engineering research and determines the result of his analysis can be expressed in terms of Complex Numbers. His result is (8-4i)(3i+2) - (5-i) Jamal simplified this expression but doesn’t trust his result. Will you help him by simplifying this complex expression?A: Explain in your own words the value of “I” and the value of “i^2” (short answers please)B: Copy the problem carefully and show all the steps needed to arrive at the final simplified answer. You must show all your work for full credit.C: write your final, simplified expression in standard complex number form for Jamal.

Accepted Solution

A:
Answer:1. The value of i is √(-1), and the value of i^2 is -1, since i*i is just √(-1)*√(-1).2. I did the first part of the equation, the multiplying of (8-4i)(3i+2), and then subtracted (5-i). Multiply equation part of the equations by each other, as down below.8*3i=24i 8*2=16 -4i*3i=12 -4i*2=-8i Combine like terms.24i-8i=16i 16+12=28 28+16iThen do -(5-i), and combine like terms.28+16i-(5-i) 28-5=2316i-(-i) =17i23+17i 3. Standard complex number form is a+bi, which I already have it in. 23+17i
