28、化简(√6+4√3+3√2)/[(√6+√3)(√3+√2)]=

28、化简(√6+4√3+3√2)/[(√6+√3)(√3+√2)]=
化简如下 (√6+4√3+3√2)/[(√6+√3)(√3+√2)]
=[(√6+√3)+3(√3+√2)]/[(√6+√3)(√3+√2)]
=(√6+√3)/[(√6+√3)(√3+√2)] + 3(√3+√2)]/[(√6+√3)(√3+√2)]
=1/(√3+√2) + 3/(√6+√3)
=(√3-√2)/[(√3+√2)(√3-√2)] + 3(√6-√3)/[(√6+√3)(√6-√3)]
=(√3-√2)+(√6-√3)
= √6-√2
