(3sqrt3)/8338

Explanation:

We can begin be re writing the square root as:

sqrt(27/64) = sqrt(27)/sqrt(64)2764=2764

Luckily, 64 is a square number so that will allow us to get rid of the square root on the bottom:

=sqrt(27)/8=278

Now we can transform sqrt(27)27 into a surd like so:

sqrt(27) = sqrt(9*3) = sqrt(9)*sqrt(3) = 3sqrt327=93=93=33

So the fraction can be re written as:

(3sqrt3)/8338
