Answer 1

Answer:

hope this will help you

Answer 2

Answer:

Step-by-step explanation:

x + 1/x = 3

(x + 1/x)^2=3^2          {squaring both sides}

x^2 + 1/x^2 + 2*x*1/x = 9                   {using (a+b)^2 = a^2 +b^2 + 2ab }

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

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

similarly again repeat the process.........

we have

x^2 + 1/x^2 = 7

(x^2 + 1/x^2)^2 = 7^2                       {squaring both sides}

x^4 + 1/x^4 + 2*x^2*1/x^2 =49                      {using (a+b)^2 = a^2 +b^2 + 2ab }

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

x^4 + 1/x^4 = 47
