Answer 1

I have no clue how to do this @ganeshie8 @kirbykirby

Answer 2

If you have a complex number \(a+ib\), then \(a\) is the real part, and \(b\) is the imaginary part.

Answer 3

so it would be -1 + 3i?

Answer 4

yeah \(\checkmark\_\checkmark\)

Answer 5

oh wait the question is not done oops!

Answer 6

Answer 7

the conjugate is \(a+ib\) is \(a-ib\)

Answer 8

don't you flip the signs to get conjugate

Answer 9

yeah
