So in this case I am actually taking the cube root of a negative number-not taking the cube root of a positive number and then negating it. Use Textbook mode and enter in -8 raised to the power of 1/3 via the template key. Then, after the calculator returns the result, change to algebraic entry. Tap the screen to copy the expression into the command line and you will see how it evaluates your original expression. Graph 3D | QPI | SolveSys |
