If `sqrt(5-12 i)+sqrt(-5-12 i)=z` , then principal value of `a rgz` can be

For z= sqrt3-i , find the principal, value arg(z)

If z=sqrt(3)-2+i , then principal value of argument z is (where i=sqrt(-1) (1) -(5pi)/(12) (2) pi/(12) (3) (7pi)/(12) (4) (5pi)/(12)

If i=sqrt(-1) , then (7+5i)(-2-6i)=

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

If z=(sqrt(3)/2+i/2)^5+(sqrt(3)/2-i/2)^5 , then prove that Im(z)=0

If z=(1+i)/sqrt2 , then the value of z^1929 is

sqrt(21-4sqrt5+8sqrt3-4sqrt12)=

If a complex number z satisfies |2z+10+10 i|lt=5sqrt(3)-5, then the least principal argument of z is

[(sqrt(5)+i/2)(sqrt(5)-i2)]-:(6+i5)

If z is any complex number satisfying abs(z-3-2i) le 2 , where i=sqrt(-1) , then the minimum value of abs(2z-6+5i) , is
