Description (last modified by )
Let the argument be positive. I think the following should give sqrt(6)
, and 6*sqrt(2)
respectively.
sage: (sqrt(2) * sqrt(3)).simplify_full() sqrt(3)*sqrt(2) sage: (sqrt(12) * sqrt(6)).simplify_full() 2*sqrt(6)*sqrt(3)
There is a Pynac ticket for this but we appreciate improvements of Maxima as well.

Replying to kcrisman:
Is this also going to simplify
sqrt(-3)*sqrt(-2)==sqrt(6)
? We've had this discussion before...
I don't remember but I hope it concluded that combining positive arguments is fine.

#12737 is the main place this sort of thing was discussed, though there are many. Probably for positive is fine, but I'm no expert on this kind of thing.
Note: See
TracTickets for help on using
tickets.
