√5x-√8=√27,x=?
√5x-√8=√27,x=?
√5x-√8=√27,x=?
√5x=√8+√27
x=(√8+√27)/√5
√5x-√8=√27
开平方则5X^2-8=27
5X^2=35
X=√30
7-6/5根号下6
若x=√2,求代数式[(x^2-2x+4)/(√x^2-4x+4)]/[(x^3+8)/(x^2-4)]*[|6-x|/(x^2-5x-6)-[1/(x^2-x+1)]^-1的值
√5x-√8=√27,x=?
xy²/(x²y-y) × x²/(x²+x)=(x²-3x)/(x²-5x) × 2x-10/(x²-6x+9)=化简求植x²-1/(x²-x-2)除以x/2x-4,其中x=1/2[x-x/(x+1)]除以[x/(2x-4)] ,其中x=√2+1
f[x -x/8-x*x]=√2 10求x^2 20x^10 x
2x=1-√5,求x^30-2x^28-x^27
y=(3x^2-x√x+5√x-9)/√x 求导
x²+4x-2=0,x²-4x+1=0,(x+√5)(x-√5)=20,x²+6x+5=8x+7,25(2x-1)²-16=0,
求极限 F(x)=(5x-7)/(2x+√x) x趋于无穷
解方程√x^2+5x-6+√3x^2-8x+5=3x-3
已知1/√(x)+√(x)=√5,求√(x/x2+x+1)+√(x/x2-x+1)的值定义域 x>0,两边平方,x+2+1/x=5,x+1/x=3,x^2-3x+1=0,x^2+x+1-4x=0,x^2+x+1=4x,x^2-x+1-2x=0.x^2-x+1=2x,√[x/(x^2+x+1)]-√[x/(x^2-x+1)]=√[x/(4x)]-√[x/2x]=√(1/4)-√(1/2)
1/(x-1)(x+1)+1/(x+1)(x+3)+1/(x+3)(x+5)+1/(x+5)(x+7)+1/(x+7)(x+9)+1/(x+9)(x+11)x=√3-5化简求值
x-√2=5x(√2-x)
x-√2=5x(√2-x)
(√x-2)+x-y-(√2-x)=5
若化简|1-x|-√x²-8x+16=2x-5,求x的取值范围.
