Square roots is a specialized form of our common roots calculator. How to use scientific calculator to calculate square root of complex numbers. This was due to the fact that in calculating the roots for each equation, the portion of the quadratic formula that is square rooted (\(b^{2}-4 a c,\) often called the discriminant) was always a positive number. An important property enjoyed by complex numbers is that every com-plex number has a square root: THEOREM 5.2.1 If w is a non–zero complex number, then the equation z2 = w has a so-lution z ∈ C. Proof. Update information
Square root Square root of complex number (a+bi) is z, if z 2 = (a+bi). Finding the Roots of a Complex Number We can use DeMoivre's Theorem to calculate complex number roots. Let's consider the complex number 21-20i. Very simple, see examples: |3+4i| = 5 |1-i| = 1.4142136 |6i| = 6 abs(2+5i) = 5.3851648 Square root Square root of complex number (a+bi) is z, if z 2 = (a+bi). The answer will also tell you if you entered a perfect square. This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. Calculators is for use with complex numbers - meaning numbers that have the form a + bi.
