Surds - Rationalising the Denominator (AQA A-Level Mathematics): Quizzes

They are not in simplified form

$\frac{\sqrt{3}}{\sqrt{3}}$

Simplified surd form

$2\sqrt{7}$

$\frac{7\sqrt{6}}{30}$

First, before rationalising

$a - b\sqrt{c}$

$7$

No, they are bad presentation

$\frac{2 + \sqrt{7}}{2 + \sqrt{7}}$
