Question

9. Rationalize of denominator of
2-73
2+V3​

Answer 1

Answer:

$\frac{2 - 73}{2 + \sqrt{3} } \times \frac{2 - \sqrt{3} }{2 - \sqrt{3} } \\ \frac{(2 - 73) \times (2 - \sqrt{3})}{ {(2)}^{2} - { (\sqrt{3} )}^{2} } \\ \frac{4 -2 \sqrt{3} - 146 + 73 \sqrt{3}}{4 - 3} \\ \frac{ - 142 + 71 \sqrt{3} }{1} = 142 + 71 \sqrt{3}$
