Rationalise the denominator of \frac{6}{\sqrt{2}}.

When rationalising, multiply the fraction by the denominator - so what that means is multiply the fraction by the square rooted number over the square rooted number. The numerators then multiply to give 6 multiplied by sqrt 2 and the denominators multiply to give sqqrt 2 multiplied by sqrt 2.
