So this: nth root of (a to the power m) becomes (nth root of a) to the power m Unit Imaginary Number. The square root of minus one √ (−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √ (−1) is i for imaginary. But in electronics the symbol is j, because i is used for current, and j is next in the alphabet.

The square root of a complex number is another complex number whose square is the given complex number. For instance, if the square root of complex number a + ib is √(a + ib) = x + iy, then we have (x + iy) 2 = a + ib. One of the simple ways to calculate the square root of a complex number a + ib is to compare the real and imaginary parts of …a, b < 0. If a and b are negative, then the square root of them must be imaginary: ⁺√a = xi. ⁺√b = yi. x and y must be positive (and of course real), because we are dealing with the principal square roots. ⁺√a • ⁺√b = xi (yi) = -xy. -xy must be a negative real number because x and y are both positive real numbers.
