Question

4. Find the modulus, Conjugate, Additive inverse and Multiplicative Inverse of the complex

number z=-1-i√3​

Answer 1

Step-by-step explanation:

Z modulus =

$\sqrt{ {x}^{2} + {y}^{2} } = \sqrt{ { - 1}^{2} + \sqrt{ - 3} {}^{2} } \\ = \sqrt{1 + 3} = \sqrt{4} = 2$

Conjugate of z =

-1 + root 3 i
