Radici di numeri complessi

Roots of Complex Numbers. We have seen that in the real number field, there are problems that aren't always possible. One of these is, for example, the impossibility of dealing with a root with an even index of a negative number. In fact, an expression containing radicals with even indexes whose radicands are negative real numbers has no meaning in the real number field. In this lesson, we will show that in the real number field, it is possible to consider any radical whose radicand is any complex number. Not only a negative real radicand, but also any imaginary number, or even more generally, any complex number. Without having to memorize formulas, we will understand how to find all the roots. Of fundamental importance are the basic notions of trigonometry, as well as the difficulty of moving from the exponential form to the algebraic form of a complex number. #salvoromeo #complexnumberroot #complexnumbers
