rac(\sqrt7 + \sqrt3)^2(\sqrt7)^2 - (\sqrt3)^2 = rac7 + 2\sqrt21 + 37 - 3 = rac10 + 2\sqrt214 = rac5 + \sqrt212. - AMAZONAWS

Solving the Interesting Equation: Rac{(√7 + √3)²}{(√7)² − (√3)²} = (7 + 2√21 + 3)/(7 − 3) = (5 + √21)/2

$rac{(\sqrt{7} + \sqrt{3})^2}{(\sqrt{7})^2 - (\sqrt{3})^2} = rac{7 + 2\sqrt{21} + 3}{7 - 3} = rac{10 + 2\sqrt{21}}{4} = rac{5 + \sqrt{21}}{2}.$
