If `x² + x +1=0` then the value of `(x+1/x)+(x^2+1/x^2)+.............(x^52+1/x^52)` equals

If x^2 - 3x +1=0, then the value of x +1/x is

If x_i>0 i=1,2,3,...50 x_1+x_2...+x_50=50 then the minimum value of 1/(x_1) +1/(x_2) +...+1/(x_50) equals

If x-1/x=0 the value x^2+1/x^2 will be

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

If x_1gt0,i=1,2.....50 and x_1+x_2+.....x_50=50 then the minimum value of 1/x_1+1/x_2+......1/x_50 equals to.

If x_(i)>0i=1,2,3,...50x_(1)+x_(2)..+x_(50)=50 then the minimum value of (1)/(x_(1))+(1)/(x_(2))+...+(1)/(x_(50)) equals
