Thanks.............

Answer 2

Answer:

x^4+1/x^4=47 is Answer

Step-by-step explanation:

x+1/x=3

on squarring both sides

(x+1/x)^2=3^2

x^2+1/x^2+2×x×1/x=9

x^2+1/x^2+2=9

x^2+1/x^2=9-2

x^2+1/x^2=7

now again squarring both sides

x^4+1/x^4+2×x^2×1/x^2=49

x^4+1/x^4+2=49

x^4+1/x^4=49-2

x^4+1/x^4=47
