If `x+1/x=8` then `x^2+1/x^2=`

If x-1/x=8 then find x^2+1/x^2 and x^4+1/x^4

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

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

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

If f(x+1/x)=x^2+1/x^2+8 then f(3), f(5), f(-1)

If x + 1/x = 8 , find the value of x^2 + 1/x^2

Find the value of : ( x^(1/2 ) + x^(-1/2 ) ) times ( x^(1/4 ) + x^(-1/4 ) ) times ( x^(1/8 ) + x^(-1/8 ) ) times ( x^(1/8 ) - x^(-1/8 ) ) ( a ) x + 1/x ( b ) ( x^2 -1 )/x

If 2^(x+6)=8^(x+1) then x=
