Jeremy Avigad	7dda69fec7	feat/refactor(library/theories/number_theory/irrational_roots,library/*): show nth roots irrational, and add lots of missing theorems	2015-08-16 23:23:23 -04:00
Jeremy Avigad	4a36f843f7	refactor(library/algebra/group_power,library/*): change definition of pow ... I changed the definition of pow so that a^(succ n) reduces to a * a^n rather than a^n * a. This has the nice effect that on nat and int, where multiplication is defined by recursion on the right, a^1 reduces to a, and a^2 reduces to a * a. The change was a pain in the neck, and in retrospect maybe not worth it, but oh, well.	2015-08-14 18:49:57 -07:00
