Question

solve without using the property of conjugates. ​

Answer 1

Step-by-step explanation:

1/z1 =( conjugate of z1)!z1)!^2

!z1! =1

so (MOD z1) ^2= 1

so

1/(z1) = conjugate of (z1)

so MOD of (1/z1+1/z2)= MOD (z1 conjugate +z2conjuagte)

MOD of z= MOD of conjugate of z( we know that so

2mod of (z1+z2)= 2*3/2=3
