" Q15.If "z=2-3i" ,find the value of "4z^(3)-3z^(2)+169

If z=2-3i, value of 4z^(3)-3z^(2)+169 will be

If z = -5 + 3i , find the value of (z^(4)+9z^(3)+26z^(2)-14z + 8) .

If z=2-3i show that z^(2)-4z+13=0 and hence find the value of 4z^(3)-3z^(2)+169

If z=2-3i show that z^2-4z+13=0 and hence find the value of 4z^3-3z^2+169.

If z=2-3i show that z^2-4z+13=0 and hence find the value of 4z^3-3z^2+169.

If z = 2-3i , show that z^2- 4z+13= 0 and hence find the value of 4z^3 - 3z^2 + 169 .

If z=2-3i show that z^2=4z+13=0 and hence find the value of 4z^3-3z^2+169.

If z=3-2i then show that z^(2)-6z+13=0 Hence find the value of z^(4)-4z^(3)+6z^(2)-4z+17

If x = 1, y = - 2 and z = 3. find the value of (i) x^(3) + y^(3) + z^3-3xyz (ii) 3xy^(4) - 15 x^(2) y + 4z

If z=(1)/(2)(i sqrt(3)-1), then find the value of (z-z^(2)+2z^(3))(2-z+z^(2))
