a + b   conjugate a - b

a - b    conjugate a + b

-z - w   conjugate -z + w

and so on.

Answer 2

Answer:

Conjugate of 6 + 7i is  6 - 7i

Step-by-step 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
