(2a根号3ab²)-(b/6根号27a³)-(6ab根号a/3)(b≥0)
(2a根号3ab²)-(b/6根号27a³)-(6ab根号a/3)(b≥0)
2a倍根号3ab²-b/6根号27a³+3ab倍根号a/3 (b大于0)
2b根号a/b+3/a根号a立方b-(4a根号b/a+根号9ab)
已知根号a(根号a+根号b)=3根号b(2/3根号a+4根号b)(ab≠0).求(a-2b+根号ab)/(a+b+根号a
化简(根号a+根号b+根号ab)方-(根号a+根号b-根号ab)方
设a>0,b>0,根号a(根号a+根号b)=3乘 根号b(根号a+5乘 根号b),求2a+3b+根号ab/a-b+根号a
(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a*根号(a^3-2a^2b+ab^2) b<0
根号a+根号b=根号3+根号2,根号ab=根号6+根号2,则a+b=
根号a^3*b-根号a*b^3-a^2*根号b/a+根号ab(a大于0,b大于等于0)
已知根号9/4-a+(b-1/4)²=0,求(a-b)/(根号a+根号b)+(a+b-2根号ab)/(根号a-
(根号a的立方b -3ab+根号ab立方)/根号ab
