Question

what is modulus of 1+2i/1-(1-i)^2​

Answer 1

Given, z=1+2i/1-(1-i)^2

z=1+2i/1-(1+i^2-2i). as,i^2=-1

so,z=1+2i/1-(1-1-2i)

z=1+2i/1+2i

z=1

so, |z|=1

Answer 2

Answer:

1

Step-by-step explanation:

Given, z=1+2i/1-(1-i)^2

z=1+2i/1-(1+i^2-2i). as,i^2=-1

so,z=1+2i/1-(1-1-2i)

z=1+2i/1+2i

z=1

so, |z|=1
