如果a根号a b根号b>a根号b b根号a
括号根号a减根号b分之a根号b减根号ab除以根号a减根号a减根号b分之b

如果你给的没错话,你直接分开计算.根号b分之a根号b可以约分的=a,根号b分之b也是可以约分的=根号b去括号可以得到:根号a/根号a-a/根号a-根号ab/根号a-根号a-根号b=1-2(根号a+根号

(根号a+根号b+根号ab)^2-(根号a+根号b-根号ab)^2.化简

﹙√a+√b+√ab﹚²-﹙√a+√b-√ab﹚²=﹙√a+√b+√ab-√a-√b+√ab﹚﹙√a+√b+√ab+√a+√b-√ab﹚=2√ab﹙2√a+2√b﹚=4﹙a√b+b

化简 a+2根号ab+b/a-b-(根号a/a+根号ab-根号b/b-根号ab)÷根号a/b+根号ab

原式=a+3√ab+ab-a+b(a-b)√ab/a(a-b)=a+3√ab+[ab-a+b-(a-b)√ab]/a(a-b)很高兴为您解答,【学习宝典】团队为您答题.请点击下面的【选为满意回答】按钮

计算a+b+2根号ab/根号a+根号b-a根号b-b根号a/根号ab

(a+b+2√ab)/(√a+√b)-(a√b-b√a)/√(ab)=(√a+√b)^2/(√a+√b)-√(ab)(√a-√b)/√(ab)=(√a+√b)-(√a-√b)=√a+√b-√a+√b=

根号a+根号b=根号3+根号2,根号ab=根号6+根号2,则a+b=

√a+√b=√3+√2(1)√ab=√6+√2(2)(2)两边平方得:ab=8+4√3(1)两边平方得:a+b+2√ab=5+2√6(3)(2)两边×2得:2√ab=2√6+2√2(4)(4)-(5)

计算:(a-2倍的根号ab+b)/(根号a-根号b)+b-a/根号a-根号b

=(√a-√b)²/(√a-√b)-(√a+√b)(√a-√b)/(√a-√b)=√a-√b-√a-√b=-2√

(根号ab-a+根号ab分之ab)除以(a-b分之根号ab-b)

[√ab-ab/(a+√ab)]÷(√ab-b)/(a-b)=(a√ab+ab-ab)/(a+√ab)×(a-b)/(√ab-b)=a√ab/√a(√a+√b)×(√a+√b)(√a-√b)/√b(√

计算 (a*根号a-b*根号a)/[a+根号(ab)]

=(a-b)*根号a/[根号a(根号a+根号b)=(a-b)/(根号a+根号b)=(根号a-根号b)(根号a+根号b)/(根号a+根号b)=根号a-根号

化简a根号a+b根号b/a+b-根号ab+a根号a-b根号b/a+b+根号ab

这题是不是这样理解的:[(a√a+b√b)/(a+b-√ab)]+[(a√a-b√b)/(a+b+√ab)],如果是的话,那么:原式=[(a√a+b√b)(a+b+√ab)/(a+b-√ab)(a+b

(a+2根号下ab+b)÷(根号下a+根号下b)-(根号下b-根号下a)=?

=(√a+√b)²/(√a+√b)-(√b-√a)=√a+√b-√b+√a=2√a

{(根号a-根号b)分之(a-b)}-(根号a-根号b)分之a+b-2根号下ab

{(a-b)/(√a-√b)}-[(a+b)-2√ab]/(√a-√b)=[(√a)^2-(√b)^2]/(√a-√b)-[(√a)^2-2√ab+(√b)^2]/(√a-√b)=√a+√b-(√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=(√b-√a+1)/√a(√a-√b)+[1/(√b-√a)-1/(√a+√b)]*(√a+√b)/2√ab=(√b-√a+1)/√a(√a-√b)+2

[根号a+(b-根号ab)/(根号a+根号b)]/[a/(根号ab+b)+b/(根号ab-a)-(a+b)/根号ab]

根号ab-ab/[a+根号(ab)]÷[根号(ab)-a]/(a-b)=根号ab-ab/[a+根号(ab)]*(a-b)/[根号(ab)-a]=根号(ab)-ab*(a-b)/(ab-a^2)=根号(

计算a-b/根号a-根号b-a+b-2根号ab/根号a-根号b悬赏30

我不知道是不是正确理解了你题目的意思(a-b)/(√a-√b)-(a+b-2√ab)/(√a-√b)=(√a+√b)(√a-√b)/(√a-√b)-(√a-√b)(√a-√b)/(√a-√b)=√a+

(根号a+b-根号ab/根号a+根号b)除以(a/根号ab+b+b/根号ab-a-a+b/根号ab)

[√a+(b-√ab)/(√a+√b)]÷[a/(√ab+b)+b/(√ab-a)-(a+b)/√ab]=[√a+(b-√ab)/(√a+√b)]÷[a/(√ab+b)+b/(√ab-a)-(a+b)

(a+2根号ab+b)/(a-b) 减去 {[根号a/(a+根号ab)减去 根号b/(b-根号ab)]}除以根号a/(b

(a+2根号ab+b)/(a-b)减去{[根号a/(a+根号ab)减去根号b/(b-根号ab)]}除以根号a/(b+根号ab)=(√a+√b)^2/(a-b)-{[√a/(a+√ab)-√b/(b-√

化简(根号a+根号b+根号ab)方-(根号a+根号b-根号ab)方

(根号a+根号b+根号ab)方-(根号a+根号b-根号ab)方=(√a+√b+√ab+√a+√b-√ab)(√a+√b+√ab-√a-√b+√ab)=(2√a+2√b)(2√ab)=4a√b+4b√a
