Please, help with this:
I have list like this, but bigger:
With one expression (function), always go one or more points (rules)
{{x^2, {x -> 2, x -> 3}}, {x^3, {x -> 5}}}
I would like results like this (pairs of x-y) but grouped in lists
according to expression(function):
{{2,2^2},{3,3^2}},{5^3}}
Please help with expression that compute this.
THX
