Question

plzzzzzzzzzz Solve it

Answer 1

Heya there !!!
Here is the answer you were looking for:
$\frac{7 \sqrt{3} }{ \sqrt{10} + \sqrt{3} } - \frac{2 \sqrt{5} }{ \sqrt{6} + \sqrt{5} } - \frac{3 \sqrt{2} }{ \sqrt{15} + 3 \sqrt{2} }$

On rationalizing the denominator we get,

$= \frac{7 \sqrt{3} }{ \sqrt{10} + \sqrt{3} } \times \frac{ \sqrt{10} - \sqrt{3} }{ \sqrt{10} - \sqrt{3} } - \frac{2 \sqrt{5} }{ \sqrt{6} + \sqrt{5} } \times \frac{ \sqrt{6} - \sqrt{5} }{ \sqrt{6} - \sqrt{5} } - \frac{3 \sqrt{2} }{ \sqrt{15} + 3 \sqrt{2} } \times \frac{ \sqrt{15} - 3 \sqrt{2} }{ \sqrt{15} - 3 \sqrt{2} } \\ \\ = \frac{7 \sqrt{3}( \sqrt{10} - \sqrt{3} )}{ {( \sqrt{10} )}^{2} - {( \sqrt{3} )}^{2} } - \frac{2 \sqrt{5}( \sqrt{6} - \sqrt{5}) }{ {( \sqrt{6} )}^{2} - {( \sqrt{5} )}^{2} } - \frac{3 \sqrt{2}( \sqrt{15} - 3 \sqrt{2} ) }{ {( \sqrt{15}) }^{2} - {(3 \sqrt{2}) }^{2} } \\ \\ = \frac{7 \sqrt{30} - 21 }{10 - 3} - \frac{2 \sqrt{30} - 10}{6 - 5} - \frac{3 \sqrt{30} - 18 }{15 - 18} \\ \\ = \frac{7 \sqrt{30} - 21}{7} - 2 \sqrt{30} + 10 - \frac{3 \sqrt{30} - 18}{ - 3} \\ \\ = \sqrt{30} - 21 - 2 \sqrt{30} + 10 + \sqrt{30} - 6 \\ \\ = - 21 + 10 - 6 \\ \\ = - 27 + 10 \\ \\ = - 17$

Hope this helps!!!
