" 5.If "x-(1)/(x)=-1," find the value of "x^(2)+(1)/(x^(2))

If x-(1)/(x)=3, find the values of x^(2)+(1)/(x^(2)) and x^(4)+(1)/(x^(4))

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

If x - 1/x = a , find the value of x^2 + 1/x^2

If x + 1/x = 8 and x - 1/x = -8 , then find the value of x^2 - 1/(x^2)

If 2^(x-1)+2^(x+1)=2560 , find the value of x.

If x^(2)+(1)/(x^(2))=18, find the values of x+(1)/(x) and -(1)/(x)

If (x^(+(1)/(2)) + x^(-(1)/(2)))^(2) = (9)/(2) , then find the value of (x^((1)/(2))-x^(-(1)/(2))) for x gt 1 .
