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

If x+1/x=5, then x^2+1/(x^2)=? (a)25 (b) 10 (c) 23 (d) 27

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

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

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

If 0ltylt2^(1//3) and x(y^(3)-1)=1 then (2)/(x)+(2)/(3x^(3))+(2)/(5x^(5)) +…=

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

The integral int[2x^[12]+5x^9]/[x^5+x^3+1]^3.dx is equal to- (A) x^10 / (2(x^5 + x^3 +1)^2) (B) x^5/ (2(x^5 + x^3 +1)^2) (C) -x^10 / (2(x^5 + x^3 +1)^2) (D) - x^5 / (2(x^5 + x^3 +1)^2)

If x+1/x=sqrt(5) , find the values of x^2+1/(x^2) and x^4+1/(x^4)

If 2(x^(2)+1)=5x , find : (i) x-(1)/(x) (ii) x^(3)-(1)/(x^(3))

Simplify the expression 8(x^(2)-x-1) + 5 (2x-2) - 3 (x^(2) +x - 1)
