Work out the division: `z(5z^2-80)-:5z(z+4)`

Work out the following divisions: z(5z^2-80) -: 5z(z+4)

Divide z(5z^(2)-80) by 5z(z+4)

Divide z (5z^2-80) by 5z(z+4)

Divide z(5z^2 – 80) by 5z(z + 4)

Work out the following divisions : 9x^2y^2 (3z – 24) -: 27xy(z – 8)

Let z_(1), z_(2), z_(3) be the roots of iz^(3) + 5z^(2) - z + 5i = 0 , then |z_(1)| + |z_(2)| + |z_(3)| = _____________.

Solve the following linear equation: 3(5z-7)-2(9z-11)=4(8z-13) .

z=i^5 then the value of (z+z^2+z^3+z^4)
