Question

simplify the following by rationalising the denominator.

Answer 1

$\frac{1}{5 - 2 \sqrt{3} } + \frac{1}{5 + 2 \sqrt{3} }$
$( \frac{1(5 + 2 \sqrt{3)} }{(5 - 2 \sqrt{3)} (5 + 2 \sqrt{3)} } = \frac{5 + 2 \sqrt{3} }{25 - 12 } = \frac{5 + 2 \sqrt{3} }{13} ) + (\frac{1(5 - 2 \sqrt{3)} }{(5 + 2 \sqrt{3)}(5 - 2 \sqrt{3}) } = \frac{5 - 2 \sqrt{3} }{25 - 12} = \frac{5 - 2 \sqrt{3} }{13} )$
$\frac{5 + 2 \sqrt{3} }{13} + \frac{5 - 2 \sqrt{3} }{13} = \frac{5 + 2 \sqrt{3} + 5 - 2 \sqrt{3} }{13}$
$= > \frac{10}{13}$
