<![CDATA[Another way of rationalising denominator]]>I like to rationalise denominators this way:
Thereβs a \( \sqrt{2}\) in the denominator, so to get rid of that, we need a \( \sqrt{2}\) in the numerator.
Luckily, \(10\) is made of \( \sqrt{2} \times 5 \sqrt{2}\).
Cancellong out the two \( \sqrt{2}\)βs in the numerator and the denominator, we get \(5 \sqrt{2}\).
