Question

If x^4-1/x2+1=8 then find the value of x

Answer 1

Answer:

form equations that is

x+1/x=3…….(i) then,

x^4+1/x^4…(ii)

now solve equation (i) to obtain the value of x;

rearranging ……(i) to obtain

x+1=3x

2x=1,dividing by 2 we obtain

x=1/2, now substituting for the value of x into equation…….(ii)

= (1/2)^4+1/(1/2)^4

= ((1/16)+1)/(1/16)

= (17/16)/(1/16)

= 17ans
