Question

if x+1/x=3 x is not equal to 0 then fond the value of x ^4+1/x^4​

Answer 1

Answer:

47

Step-by-step explanation:

x+1/x=3

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

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

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

x^2+1/x^2=9-2=7

now same way

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

7^2=x^4+1/x^4 +2

x^4+1/x^4=49-2=47
