`" If "z=sqrt((1-i)/(1+i))" ,then arg z"=`

If z=((1+i sqrt(3))/(1+i))^(25), then arg(z) is equal to

If z=(1+2i)/(1-(1-i)^(2)), then arg (z) equals a.0 b.(pi)/(2) c.pi d .non of these

If "|z-i|=1 &"Arg(z)=(pi)/(2)" then the "z" is (1) "-2i" (2) "0" (4) "2i"

If |z_(1)| = sqrt(2), |z_(2)| = sqrt(3) and |z_(1) + z_(2)| = sqrt((5-2sqrt(3))) then arg ((z_(1))/(z_(2))) (not neccessarily principal)

If z = (-4 +2 sqrt3i)/(5 +sqrt3i) , then the value of arg(z) is

If z = sqrt(20i-21)+sqrt(21+20i) then the value of |arg z^(4)| is

The complex number z which satisfy the equations |z|=1 and |(z-sqrt(2)(1+i))/(z)|=1 is: (where i=sqrt(-1) )

If z_(1)=1+i,z_(2)=sqrt(3)+i then arg((z_(1))/(z_(2)))^(50) is
