根号下(x-5)^2+(0+12)^2=13,怎么算根号下(x-5)^2+(0+12)^2=13,怎么算根号下(x-5)^2+(0+12)^2=13,怎么算(x-5)^2+12^2=13^2(x-5)
根号下(x-5)^2+(0+12)^2=13,怎么算
根号下(x-5)^2+(0+12)^2=13,怎么算
根号下(x-5)^2+(0+12)^2=13,怎么算
(x-5)^2+12^2=13^2
(x-5)^2=13^2-12^2=(13-12)(13+12)=25
(x-5)=+-5
x=0或者10
若x>0,y>0,且根号下x(根号下x+根号下y)=3根号下y(根号下x+5根号下y),求(2x+2根号下若x>0,y>0,且根号下x(根号下x+根号下y)=3根号下y(根号下x+5根号下y),求(2x+2根号下xy+3y)/(x-根号下xy+y
请问 根号下3x-3 +根号下5x-19 -根号下2x-8=0
(x-根号下2)=根号下5×x(2-根号下2×x)
解方程:根号下x+8-根号下5x+20 +2=0
解方程 1.(x-根号下3)²=2 2.2*(3x-根号下2)²=8 化简 1.5/根号下5+根号下5/4-1/4*根号下802.(根号下12-根号下4/3)-2*(根号下1/8-1/根号下2-根号下18)
根号下(x平方+5x-14)+根号下(x+7)+根号下(2-x)+x-5=0的根RT

如果 根号下x-根号下y等于根号下3+根号下2 根号下xy等于根号下6-根号下2 则 x+y=?
如果根号下(3-X)^2=X-3,根号下(x-5)=5-x,化简根号下(36-12x)^2+根号下x^2-20x+100
