Could someone please explain why cube root(-343) doesn't equal (-343)^(1/3) on both Wolfram Alpha and my HP-48 calculator.
cube root(-343)= -7, yet (-343)^(1/3)= 3.5 +6.062177... i
Look for where it says "Assuming the principal root | Use the real‐valued root instead."
That link will give you
I don't even know the maths of roots other than the square root, so I can't even tell for sure what I want to expect as result. All I need to know is that in Mathematica you can enter/handle the radical expression either with Ctrl+, with Power, with Surd, or with CubeRoot.
So Raspi, do you have any specific questions on how to use other roots in Mathematica?
Hi @Marvin , I don't have questions regarding such roots in Mathematica. But maybe the thread starter @Liam has some?
