Question

(3+4i)^2

(2+4i)(7-8i)

Answer 1

10 (-61 + 102 i)

(3 + 4 i)^2 (2 + 4 i) (7 - 8 i)

Explanation:

(3 + 4 i)^2 (2 + 4 i) (7 - 8 i)

10 (-61 + 102 i)

r = 50 sqrt(565) (radio), θ = π - tan^(-1)(102/61) (ángulo)

50 sqrt(565) (cos(π - tan^(-1)(102/61))+i sin(π - tan^(-1)(102/61)))

50 sqrt(565) e^(i (π - tan^(-1)(102/61)))

x^2 + 1220 x + 1412500
