Given that x =7 + √3
===================
1/x = 1/(7 + √3)
By Rationalization,
×
===============================
Then,
x² = (7 + √3)²
= 49 + 3 + 14√3
= 52 + 14√3
AND
1/x² =
1/x² =
1/x² =
===========================
x² + 1/x² = 52 + 14√3 + (52 - 14√3)/2116
= (110032+ 29624√3 + 52 - 14√3)/2116
= (110084 + 29610√3)/2116
