Can you explain what a complex conjugate is?
Can you explain what the reciprocal of a complex number is?

what i understand is if a+bi is any complex number then a-bi is its complex conjugate.. and 1/(a-bi) is reciprocal of complex conjugate

You are correct about the complex conjugate.

For the reciprocal of the the complex conjugate the best explanation is the one I found in Wikipedia at:
