根号a加根号b等于根号2009,求a,b
a,b为整数
a,b为整数
2009 = 7*7*41
根号2009 = 7根号41
根号a + 根号b = 根号2009 = 7根号41
(1):根号a = 6根号41;根号b = 根号41
a = 1476;b = 41
(2):根号a = 5根号41;根号b = 2根号41
a = 1025;b = 164
(3):根号a = 4根号41;根号b = 3根号41
a = 656 ;b = 369
(4):根号a = 根号2009;根号b = 0
a = 2009 ;b =0
综上,有4种:
(1476,41)
(1025,164)
(656 ,369)
(2009 ,0)
根号2009 = 7根号41

根号a加根号b等于根号1998,求a加b的值.
已知a+b等于6,ab等于4,求根号a加根号b分之根号a减根号b
求根号a加根号b分之根号a减根号b a加b等于根号ab a大于b大于0
已知a加b等于根号下根号2002加根号2001,a减b等于根号下根号2002减根号2001,求ab的值
已知a 、b是正整数,且根号a加根号b等于根号1998,求a加b的值?
根号a加根号b等于根号5加根号3,根号ab等于根号15减根号3,则a加b等于?
3次根号负8等于a,根号b=16,求a加b
a加b等于负4,ab等于2求根号b分之a加根号a分之b
已知根号a加根号b等于根号3加根号2,根号下a乘b等于根号6减根号3,求a加b的值
(根号a加根号b加1)乘以(1减根号a加根号b)减(根号a加根号b)的平方等于多少
根号ab加2根号a分之b减b根号b分之a等于多少
如果根号a加根号b等于根号c且都是同类二次根式,根号a加根号b等于根号1998,a,b均为正整数,求a加b
