Question

find the modulus,conjugate,additive inverse and multiplicative inverse of the complex number z=-1-i✓3​

Answer 1

Answer:

modulus of z=-1-i✓3

√(-1)^ + (-✓3)^

√1+3

√4 =2

conjugate of -1-i✓3 is

-1+i✓3

additive inverse of z=-z

so -1-i✓3

is l+i✓3

multiplicative inverse of -1-i✓3

is l+i✓3/(1)^+(✓3)^

= 1+i✓3/1+3

=1+i✓3/4
