<根号b-根号a +1 >/ a-根号ab +<根号b/b-根号ab - 根号a/a+根号ab>除以2根号ab/根号a+根号b怎么计算?

/ a-根号ab +除以2根号ab/根号a+根号b怎么计算?
<根号b-根号a +1 >/ a-根号ab +<根号b/b-根号ab - 根号a/a+根号ab>除以2根号ab/根号a+根号b
=(√b-√a+1)/√a(√a-√b)+[1/(√b-√a)-1/(√a+√b)]*(√a+√b)/2√ab
=(√b-√a+1)/√a(√a-√b)+2√a/(√b-√a)(√a+√b)*(√a+√b)/2√ab
=(√b-√a+1)/√a(√a-√b)+1/√b(√b-√a)
=[(b-√ab+√b)-a]/√ab(√a-√b)
