If `x^2-x-1=0` then the value of `x^8+1/x^8` equals

If x^2-3x-1=0 , then the value of (x^2+ 8x-1)(x^3+x^(-1))^-1 is: यदि x^2-3x-1=0 है, तो (x^2+ 8x-1)(x^3+x^(-1))^-1 का मान क्या होगा ?

If 4x^2-6x+1=0 , then the value of 8x^3 +(8x^3)^-1 is: यदि 4x^2-6x+1=0 है, तो 8x^3 +(8x^3)^-1 का मान ज्ञात करें |

If 2^(x)-2^(x-1)=8 , then the value of x^(3) is :

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

If x^(2)-3x+1=0 , then one of the values of (x^(2)-8x-1)/(x^(3)+1//x) is :

If x-(1)/(x)=1, then the value of x^(3)-(1)/(x^(3)) is equal to (a)2(b)3(c)4(d)8
