Here is the definition of conjugate:
In algebra, a conjugate is a binomial formed by negating the second term of a binomial. The conjugate of x + y is x − y, where x and y are real numbers.

Hopefully this helps you for your question.

Answer 2

my guess is that \(j=\sqrt{-1}\)
if so, then the conjugate of \(7j\) is \(-7j\)

Answer 3

Thank you, I do know that but it says I have to answer in a+bj format. Im not sure how to write that.

Answer 4

\(0-7j\) if you want to be silly and write in the format it asked for

Answer 5

I believe that it means to do the inverse of what is required. Meaning to do the inverse operation.

Answer 6
