if `x+1/x=5` the value of `(x^4+1)/x^2` is

If x-1/x=2, then the value of x^4+1/x^4 is :

If (x-1/x)=4 then the value of (x^2+1/x^2) is

If (x+1/x) =2 then the value of (x^5+1/x^5) is:

If x^2-5x+1=0 , then the value of (x^4+1/x^2) div (x^2+1) is : यदि x^2-5x+1=0 , तो (x^4+1/x^2) div (x^2+1) का मान ज्ञात करें:

If x^(2)-5x+1=0 , then the value of (x^(4) + (1)/(x^(2))) div (x^(2)+1) is
