Given that \(x + \frac{1}{x} = 8\)
We want to find
\(x^2 + \frac{1}{x^2}\)
We can use the identity:
\(x^2 + \frac{1}{x^2} = \left( x + \frac{1}{x} \right)^2 - 2\)
Substituting the given value:
\(x^2 + \frac{1}{x^2} = 8^2 - 2\)
Calculating \( 8^2 \):
\(8^2 = 64\)
Now substituting back:
\(x^2 + \frac{1}{x^2} = 64 - 2 = 62\)
Thus, the final answer is \(x^2 + \frac{1}{x^2} = 62\)
