Answer 1

Answer:

$70 + 14 \sqrt{3}$

Step-by-step explanation:

$\frac{5 + \sqrt{3} }{7 - 4 \sqrt{3} } + \frac{5 + \sqrt{3} }{7 + 4 \sqrt{3} }$

rationalization of denominator..

$\frac{5 + \sqrt{3} }{7 - 4 \sqrt{3} } \times \frac{7 + 4 \sqrt{3} }{7 + 4 \sqrt{3} } + \frac{5 + \sqrt{3} }{7 + 4 \sqrt{3} } \frac{7 - 4 \sqrt{3} }{7 - 4 \sqrt{3} }$

solve..

$\frac{(5 + \sqrt{3})(7 + 4 \sqrt{3}) }{49 - 16 \times 3} + \frac{(5 + \sqrt{3} )(7 - 4 \sqrt{3} )}{49 - 16 \times 3}$

Or

$\frac{(5 + \sqrt{3})(7 + 4 \sqrt{3}) }{49 - 48} + \frac{(5 + \sqrt{3} )(7 - 4 \sqrt{3} )}{49 - 48}$

Or

$(5 + \sqrt{3})(7 + 4 \sqrt{3}) + (5 + \sqrt{3})(7 - 4 \sqrt{3})$

Or

$35 + 20 \sqrt{3} + 7 \sqrt{3} + 12 + 35 - 20 \sqrt{3} - 12$

Or

$35 + 7 \sqrt{3} + 35 + 7 \sqrt{3}$

Add them

$70 + 14 \sqrt{3}$

So we reach to an End...
