One can use for example

from sympy import simplify
simplify(sqrt(21)*sqrt(6))

3*sqrt(14)

giac('simplify(sqrt(21)*sqrt(6))')

3*sqrt(14)

giac('normal(sqrt(21)*sqrt(6))')    

3*sqrt(14)

maxima('rootscontract(sqrt(21)*sqrt(6))')

3*sqrt(14)

(sqrt(21)*sqrt(6)).canonicalize_radical()

3*sqrt(7)*sqrt(2)
