Does anybody have a package to denest radicals, e.g. to convert Sqrt[1205 + 560 10^(1/3) + 260 10^(2/3)] into Sqrt[5] (9 + 4 10^(1/3) + 2 10^(2/3))?

@b3m2a1 That works for specific instances, I was hoping there would be a way to do it generally since I have a lot of such values with different amounts of radians in them. I ended up writing a function using UnitDimensions

stripRadians[q_] :=
 q*Quantity[
   "Radians"^-Association[#[[1]] -> #[[2]] & /@
        UnitDimensions@q][["AngleUnit"]]]

I do wonder if there's a better way to get the "AngleUnit" part of something like {{"AngleUnit", -1}, {"LengthUnit", 1}} without that weird blob converting it to an Association

@Pavel Normal should be able to remove angles from quantities, but it seems to fail when the "Radians" unit is part of a compound unit.

@CarlLange This is one of those (many many) moments where just talking to people on the internet makes a big improvement in one's life. I'd read about TypeScript before but forgotten about it and it's really making life better in a Markdown-annotator I'm writing.

I make pretty extensive use of PyCharm's type-hinting in Python and it's really nice to have that kind of help with Javascript too, especially given that I don't know Javascript well...
