The nth root is denoted r=RadicalBox[z, n] or, using power notation, r=z^(1/n). The special case of the square root (n=2) is denoted sqrt(z). The case n=3 is known as the cube root. The quantities for which …

If A ∈ M 2 × 2 ( C) is a nonzero nilpotent matrix, then a square-root of the matrix A is not defined. To see this, Suppose that A = ( 0 1 0 0) = B 2, then B is nilpotent as well. Then B is similar to either A or O (zero-matrix), by considering Jordan block. But, in either case, B 2 = O, which is not possible. Share.
