Question 70005
{{{sqrt(2)/sqrt(7)}}}

Multiply both the numerator and the denominator by {{{sqrt(7)}}}

{{{(sqrt(2)*sqrt(7))/(sqrt(7)*sqrt(7))}}}

The denominator multiplies out to become 7 and the numerator becomes {{{sqrt(14)}}}

So the answer is {{{sqrt(14)/7}}}

The reason for simplifying the original problem, is that convention says to never leave a
radical in the denominator.  Get rid of it by multiplying it by itself.

Hope this helps you.
