Question

after rationalise the denominator of 2÷3-√7 we get​

Answer 1

$\frac{2}{3 - \sqrt{7} } \\ = \frac{2}{3 - \sqrt{7} } \times \frac{3 + \sqrt{7} }{3 + \sqrt{7} } \\ = \frac{2(3 + \sqrt{7}) }{ {(3)}^{2} - {( \sqrt{7} )}^{2} } \\ = \frac{2(3 + \sqrt{7}) }{9 - 7} \\ = \frac{2(3 + \sqrt{7}) }{2} \\ = 3 + \sqrt{7}$

Hence, your answer is 3+√7✌

Answer 2

Step-by-step explanation:

3−72=3−72×3+73+7=(3)2−(7)22(3+7)=9−72(3+7)=22(3+7)=3+7
