If `x+(1)/(x)=7`, then find
(i) `x^(3)+(1)/(x^(3)) `
(ii) `x^2 + 1/x^2`

If x+(1)/(x)=7 ,then find x^(3)-(1)/(x^(3))

If x^(2)-2x+1=0 then find (i)x^(3)+(1)/(x^(3))(ii)x^(4)+(1)/(x^(4))(iii)x^(2)-(1)/(x^(2))(iv)x^(2)+(1)/(x^(2))

If x^(2)+(1)/(x^(2))=7; find the value x^(3)-(1)/(x^(3))

If x=3-2sqrt(2) then find (i)x^(2)-(1)/(x^(2))(ii)x^(2)+(1)/(x^(2))(iii)(x-(1)/(x))^(3)

If x^(2)+(1)/(x^(2))=7, find the value of x^(3)+(1)/(x^(3))

If 1lt(x-1)/(x+2)lt7 then find the range of (i) x (ii) x^(2) (iii) (1)/(x)

If x +(1)/(x) =2 , find the value of (x^2 +(1)/(x^2))(x^3 +(1)/(x^3))

If x^(2)+3x+1=0 then find x^(3)+(1)/(x^(3)),x^(4)+(1)/(x^(4)),x^(2)-(1)/(x^(2)),x^(2)+(1)/(x^(2))

(b) If (x^(2)+1)/(x)=3(1)/(3) and x>1 ; find x^(3)-(1)/(x^(3))

If x=3+2sqrt(2) , then find : (i)(1)/(x)" "(ii)x+(1)/(x)" "(iii)x-(1)/(x)" "(iv)x^(2)-(1)/(x^(2))
