In `z=5/(1-3i) ` then find `z.bar z`.

If z=(3+4i)/(5i) then find zbar z

If z=(3+4i)/i ,then find |z|

If sin^(-1) x +sin^(-1)y +sin^(-1) z =(3pi)/(2) , then find the value of x^(100) +y^(100) +z^(100) -(9)/(x^(101)+y^(101)+z^(101)) .

If [(5,3x),(2y,z)]=[(5,4),(12,6)] , then find y.

Find x+y+z

If z=1-i ,then mention the value of arg(z).

If z=1+i ,then mention the value of arg(z) .

If 1/2 , x, y, z, 128 are in G.P., then find x,y,z,

Find Z-(R-Z) .
