WebSep 16, 2024 · First, convert each number to polar form: z = reiθ and i = 1eiπ / 2. The equation now becomes (reiθ)3 = r3e3iθ = 1eiπ / 2. Therefore, the two equations that we need to solve are r3 = 1 and 3iθ = iπ / 2. Given that r ∈ R and r3 = 1 it follows that r = 1. Solving the second equation is as follows. First divide by i. WebComplex roots are the imaginary roots of quadratic equations which have been represented as complex numbers. The square root of a negative number is not possible and hence we transform it into a complex number. The quadratic equations having discriminant values lesser than zero b 2 - 4ac < 0, is transformed using i 2 = -1
