√a(√a+√b)=3√b(2/3√a+4√b),其中ab不等于0,求a-5b+√ab/a+b+√ab的值?

√a(√a+√b)=3√b(2/3√a+4√b),其中ab不等于0,求a-5b+√ab/a+b+√ab的值?
√a(√a+√b)=3√b(2/3√a+4√b),其中ab不等于0,求a-5b+√ab/a+b+√ab的值?

√a(√a+√b)=3√b(2/3√a+4√b),其中ab不等于0,求a-5b+√ab/a+b+√ab的值?
√a(√a+√b)=3√b(2/3√a+4√b)=>
a-12b-√(ab)=0
(√a-4√b)(√a+3√b)=0
=>√a=4√b
=>a=16b
(a-5b+√ab)/(a+b+√ab)
=(16b-5b+4b)/(16b+b+4b)=5/7
