Answer 1

$\frac{( 3 \sqrt{5} - 2 \sqrt{7} ) \times ( \sqrt{7} + \sqrt{11} )}{( \sqrt{7} - \sqrt{11}) \times ( \sqrt{7} + \sqrt{11} ) } \\ \frac{3 \sqrt{35} + 3 \sqrt{55} - 2 \times 7 - 2 \sqrt{77} }{ { \sqrt{7} }^{2} - { \sqrt{11} }^{2} } \\ \frac{3 \sqrt{35} + 3 \sqrt{55} - 14 - 2 \sqrt{77}}{7 - 11} \\ \frac{3 \sqrt{35} + 3 \sqrt{55} - 14 - 2 \sqrt{77} }{ - 4} \\ \frac{ - 3 \sqrt{35} - 3 \sqrt{55} + 14 + 2 \sqrt{77} }{4}$
