The trick to simplifying radicals is writing the number under the radical sign as a product of a perfect square and the smallest possible number.
Sometimes the prime factorization helps. Other times, I see it without thinking of prime factors. For example, I know that 50=2%2A25 and that 25 is a perfect square (25=5%5E2).
I am going to use 54=6%2A9 and 18=2%2A9 too.
