Question

If x = 9 + 4sqrt(5) and xy = 1 , then find the value of 1/322 * (1/(x ^ 2) + 1/(y ^ 2))
$x = 9 + 4 \sqrt{5 \: } and \: xy = 1 \: \: then \: find \: \frac{1}{322} \times ( \frac{1}{{x}^{2} } ) + ( \frac{1}{{y}^{2} } )$
​please answer

Answer 1

If x = 9 + 4sqrt(5) and xy = 1 , then find the value of 1/322 * (1/(x ^ 2) + 1/(y ^ 2))

$x = 9 + 4 \sqrt{5 \: } and \: xy = 1 \: \: then \: find \: \frac{1}{322} \times ( \frac{1}{{x}^{2} } ) + ( \frac{1}{{y}^{2} } )$
