化简:根号5+根号3减根号2/8+2根号15+根号10减根号6
化简(8+2根号5-根号10-根号6)/(根号5+根号3-根号2)
根号2、根号3、根号5、根号6、根号7、根号8、根号10等根号20以内的约数
(5+根号6+根号10+根号15)除以(根号2+根号3+根号5)
(根号1+根号2+根号3+根号4+根号5+根号6+根号7+根号8+根号9+根号10)÷2
根号1+根号2+根号3+根号4+根号5+根号6+根号7+根号8+根号9+根号10等于多少
计算:(8+2根号15-根号10-根号6)/(根号5+根号3-根号2)
化简 1.(跟号3+根号5)除以(3-根号6-根号10+根号15) 2.2根号6除以(根号2+根号3+根号5)
(根号5+根号2+根号3)乘(根号5减根号2减根号3)=
化简:根号2+根号3/根号10+根号14+根号15+根号21
(根号8+根号3)乘根号6-根号5/根号10-根号15
1*根号2*根号3*根号5*根号6*根号7*根号8
