Answer 1

Answer:

$( \sqrt{5} + \sqrt{3}) \div (\sqrt{5} - \sqrt{3 }) = ( \sqrt{5} + \sqrt{3} )( \sqrt{5} + \sqrt{3} ) \div ( \sqrt{5} - \sqrt{3} )( \sqrt{5} + \sqrt{3} ) = (5 + 2 \sqrt{15 } + 3) \div( 5 - 3) = 8 + 2 \sqrt{15 } \div 2 = 2(4 + \sqrt{15}) \div 2 = 4 + \sqrt{15} \\ hope \: this \: helps \: you$
