(1)/(x+5)=(1)/(x^(2))

(3)/(x+1)-(2)/(x-1)=(5)/(x^(2)-1)

lim_(x rarr0)(1^((1)/(x))+3^((1)/(x))+5^((1)/(2)))^(x)

Solve x:(3x-1)/(5)=(1+x)/(2)=3-(x-1)/(4)

value of the limit when x tends to unity of the expression ([(3+x)^((1)/(2))-(5-x)^((1)/(2))])/(x^(2)-1) is

Number of integral values of x which satisfy the inequality log_(x+(1)/(x))(1+5x-x^(2))>0, is :

If (x - (1)/(x)) = 5 then (x^(2) + (1)/(x^(2))) = ?

If x = (1)/(x- 5) , find: x^(2)- (1)/(x^(2))

If x = (1)/(x- 5) , find: x^(2) + (1)/(x^(2))
