Hello.

I have a lot of lists of integers and I want to sum their Xth power automatically, for X = -3, -2, -1, -1/2, 0, 1/2, 1, 2, 3, 4, 5, 6.

For example, take this short list of integers: 1 2 3 4 6 12

The sum of their Xth power must be: 1^X + 2^X + 3^X + 4^X + 6^X + 12^X

How can I do that?

Thanks in advance for your answers.
