Question

Subtract (5 − 2i) − (1 + 8i). What is the real part of the difference? What is the imaginary part of the difference? i

Answer 1

Real part of the difference is: 4

and imaginary part of the difference is: -10

Explanation:

We have to find (5 − 2i) - (1 + 8i)

(5 − 2i) − (1 + 8i)

= 5 - 2i -1 - 8i

= (5-1) - i(2+8)

= 4 - 10i

Hence, Real part of the difference is: 4

and imaginary part of the difference is: -10

Answer 2

Answer: 4-10i. The real part is 4, and the imaginary part is -10i.

Step-by-step explanation: Treat i as just a variable, and use simple algebra. By simplifying, it just turns out to be 5-1, and -2i-8i, thus leading to 4-10i.
