Find the modulus of:

(a) (3 – j4) (-5 + j12)

(b) (2+?)/(4?+(1+?)^2)

Express (6 – ?8)^−3 in the standard form ? + ??. Find its conjugate.

If ? + ?? = (?+?)/ (?−?) ,where a, b and c are real, prove that ?^2 + ?^2 = 1 and ?/?= (2?)/ (?^2−1)

Please show all your steps so I can understand

Thank you
