Cube root negative number
Web4 I am trying to compute the cube root of a negative number in VBA for Excel. Taking the cube root of a negative number in an Excel worksheet works fine: = (-2)^ (1/3) -1.25992 However the same concept coded into VBA: (-2)^ (1/3) gives a #VALUE! error when returning the value to the worksheet. WebA cube root can be negative if the radicand (number under the radical) is also negative. For example, the cube root of -8 is -2, since (-2) 3 = (-2) (-2) (-2) = -8 (a negative raised to an odd power is always negative). Another way …

WebGuided notes teaching how to graph square root and cube root functions by translating the parent function. I teach my students to use the "base points" [ (0, 0), (1, 1), and (4, 2) or (-1, -1) for square/cube root] and then transform them using (h, k) or vertex form. They also must be able to determine transformations and equations from a graph. WebOne square root of 36 is 6 since 6² = 36. 36 also has a negative square root, since (-6)² = 36 . ...
