Can anyone proove why {x^n} /\sum_{0}^{x}x^{n-1}={x-1}/x

Could you rewrite,please ??

Daniel.

Rewrite done.

It doesn't look sound to me.If you sum over "x",why doesn't "n" appear in the equation...?

Also, in its current form, the Right Side is 0 at x=(1), whereas the Left Side is non-zero at x=(1).

There's definitely something weird with this exercise.Maybe he'll explain it,or or just drop it...
