I would like help with a very trivial question: When I make calculations, I get things like this: Sqrt[a] Sqrt[b] Sqrt[c]. I would like to get Sqrt[a b c]. Thank you very much
One way
Simplify[Sqrt[a] Sqrt[b] Sqrt[c], {a > 0, b > 0, c > 0}] (* Sqrt[a b c] *)
Simplify[Sqrt[a]*Sqrt[b]*Sqrt[c], Assumptions -> Element[{a, b, c}, NonNegativeReals]] (* Sqrt[a b c] *)
