Consider the given equation `11 z^10 + 10 i z^9 + 10 i z - 11 =0`, then |z| is

Given that z^2 - 10z + 25 = 9 , what is z?

Solve the following equations : 5z+11=9z+2

Find the value of z^3-3(z-10) for z=10

If z = 3- 5i then z^(2) - 10z + 30=

Consider the complex number z_1 = 2 - i and z_2 = 2 + i Find 1/(z_1z_2) . Hence, prove than I_m(1/(z_1z_2)) = 0

If A=[[1,-2,1],[0,-1,1],[2,0,-3]] then find A^(-1) and hence solve the system of equations x-2y + z = 0 , -y + z = -2 and 2x-3z= 10.
