WebAs we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": If a < b then −a > −b. If a > b then −a < −b. This is really the same as multiplying by (-1), and that is why it changes direction. Example: Alex has more money than Billy, and so Alex is ahead. Web6 Oct 2024 · Definition 8.1.16. Given a real number a and a positive integer n, an “ nth root of a” is a number x such that xn = a. For example, 2 is a 6th root of 64 since 26 = 64 and −3 is a fifth root of −243 since ( − 3)5 = − 243. The case of even roots (i.e., when n is even) closely parallels the case of square roots. tau trasfondo
