Question

rationalise the following [7×√3] /√10+√3​

Answer 1

Step-by-step explanation:

$\frac{7 \sqrt{3} }{ \sqrt{10} + \sqrt{3} } \\ \frac{7 \sqrt{3} }{ \sqrt{10} + \sqrt{3} } \times \frac{ \sqrt{ 10} - \sqrt{3} }{ \sqrt{10} - \sqrt{3} } \\ \frac{7 \sqrt{3}( \sqrt{10} - \sqrt{3}) }{10 - 3} \\ \frac{7 \sqrt{3}( \sqrt{10} - \sqrt{3}) }{7} \\ \sqrt{3} ( \sqrt{10} - \sqrt{3} ) \: \: \: \: \: \: \: or \: \: \: \: \: \: (\sqrt{30} - 3)ans$
