回答1:

根号6/(√3+√2)+(√3-√2)/√6
=√6(√3-√2)+√6(√3-√2)/6
=(3√2-2√3)+(3√2-2√3)/6
=7(3√2-2√3)/6
=21√2/6-14√3/6
=7√2/2-7√3/3

回答2:

√6/(√3+√2)+(√3-√2)/√6
=√6(√3-√2)+√6(√3-√2)/6
=(3√2-2√3)+(3√2-2√3)/6
=7(3√2-2√3)/6
=21√2/6-14√3/6
=7√2/2-7√3/3

回答3:

√6/(√3+√2)+(√3-√2)/√6
=√6(√3-√2)+√6(√3-√2)/6
=√6(√3-√2)*(1+1/6)
=(7/6)*(3√2-2√3)
=(21√2-14√3)/6
