化简:(√a²+a√b)/(ab-b²)-(a+√ab+b)/(a√a-b√b)

化简:(√a²+a√b)/(ab-b²)-(a+√ab+b)/(a√a-b√b)
化简:(√a²+a√b)/(ab-b²)-(a+√ab+b)/(a√a-b√b)

化简:(√a²+a√b)/(ab-b²)-(a+√ab+b)/(a√a-b√b)
(√a²+a√b)/(ab-b²)-(a+√ab+b)/(a√a-b√b)
= (a+a√b)/[b(a-b)] - (a+√ab+b) / [(√a)³-(√b)³]
= (a+a√b)/[b(a-b)] - (a+√ab+b) / [(√a-√b)(a+√ab+b) ]
= (a+a√b)/[b(a-b)] - 1 / (√a-√b)
= (a+a√b)/[b(a-b)] - (√a+√b) / (a-b)
= (a+a√b)/[b(a-b)] - (b√a+b√b) / [b(a-b)]
= (a+a√b-b√a-b√b) / [b(a-b)]
