Question

If z=1+i, then the muliplicative inverse of z2 is (where
i=1-1)
(a) 2 i
(b) 1-i
(C)
(d)
2
2.​

Answer 1

Answer:

mutiplicative inverse means reciprocal. answer is 1/2

Step-by-step explanation:

here i = 1-1

and z=1+i

so, z=1+(1-1)

z=1

we want to find mutiplicative inverse of z2 and z=1

so, z2=1*2=2

and mutiplicative inverse of 2 is 1/2
