若a,b满足a^2b^2+a^2+b^2+10ab+16=0,求a^2+b^2的值

若平面向量a,b满足|2a-b| 若非零向量a,b满足/a+b/=/b/,证明/2b/>/a+2b/ 有理数ab满足a+b＜0.化简|a+b|+(-a)+(-b)+2a+2b 若实数a,b,c满足a^2+a+bi 已知实数a,b满足a>b,求证：-a^2-a＜-b^3-b 若正数a,b满足a+b=1,则a^2+b^2的最小值 若实数a,b满足a+b=2,求3^a+3^b的最小值 若实数a,b满足a+b=2则3^a+3^b最小值是 若不等式b/a+a/b>2成立,则a,b必须满足的条件 若不等式b/a+a/b>2成立,则a与b满足的条件是? 若向量a,b满足:|a|=1,(a+b)⊥a,(2a+b)⊥b则|b|=A.2 B.根号2 C.1 已知向量a,b满足（a+2b）… 若a,b满足{a+2b=8,2a+b=7则a-b= 若a、b 满足a²+b²+4/5=a-2b 求2a-3b 若实数a,b满足a*b-4*a-b+1=0求(a+1)*(b+2)的最小值 若非零向量a,b满足/a+b/=/b/,则若非零向量a.b满足|a+b|=|b|,则 A.|2a|>|2a+b| B.|2a||a+2b| D.|2b| 6.若非零向量a b满足|a-b|=|b|,则A.|2b|>|a-2b|B.|2b||2a-b|D.|2a| 若非零向量a b满足|a-b|=|b|,则A.|2b|大于|a-2b|B.|2b||2a-b|D.|2a|
