z^2+1/z^2 = 34
(z+1/z)^2 = z^2+1/z^2 +2
34+2 = 36
z+1/z = 6
Cubing on both sides
(z+1/z)^3 = 6^3
z^3+1/z^3+3(z+1/z) = 216
z^3+1/z^3+3×6 = 216
z^3+1/z^3+ 18 = 216
z^3+1/z^3 = 216-18
z^3+1/z^3 = 198
Question 30 you do it by this example
(z+1/z)^2 = z^2+1/z^2 +2
34+2 = 36
z+1/z = 6
Cubing on both sides
(z+1/z)^3 = 6^3
z^3+1/z^3+3(z+1/z) = 216
z^3+1/z^3+3×6 = 216
z^3+1/z^3+ 18 = 216
z^3+1/z^3 = 216-18
z^3+1/z^3 = 198
Question 30 you do it by this example
