1/((1+x)^0.5+(1+x)^(1/3))的积分,1/((1+x)^0.5+(1+x)^(1/3))的积分,1/((1+x)^0.5+(1+x)^(1/3))的积分,有点错倒数二行=2t
1/((1+x)^0.5+(1+x)^(1/3))的积分,
1/((1+x)^0.5+(1+x)^(1/3))的积分,
1/((1+x)^0.5+(1+x)^(1/3))的积分,
有点错
倒数二行
=2t³+3/2t⁴
=2(1+x)^0.5+3/2(1+x)^(2/3)+C
x/x+(1-x)/x-1/x

(x+1)(x-1)(x-x+1)(x+x+1)
分解因式----(X*X-X)(X*X-X-2)+1
X(X-1)=X
1.1/x|x/(x+1)|
求x:|x|-|x-4|=0.5x-1
x/x-1[1+(x-1/x)]
x-1/x÷(x-1/x)
】x(x+1)+x^2(x-1)
1/(1-x)+1/(1+x)+2/(1+x*x)+4/(1+x*x*x*x)+8/(1-x*x*x*x*x*x*x*x)怎么做
x=1+0.5x+0.25x+0.125x+0.0625x求x的值
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
x>1/1-x
x+1/x-1
(X + 1) /(x - 1)
