the conjugate of any pair is just the same pair with a different sign in the middle.

a + b conjugate a - b

a - b conjugate a + b

-z - w conjugate -z + w

and so on.

Answer 2

Conjugate of 6 + 7i is 6 - 7i

Explanation:

Conjugate of a + ib is given by a - ib

Here we need to find conjugate of 6 + 7i.

That is a + ib = 6 + 7i

a = 6 and b = 7

Conjugate of a + ib is a- ib

So conjugate of 6 + 7i is given by 6 - 7i

Conjugate of 6 + 7i is 6 - 7i
