Aim: How do we simplify radicals?

The way we can simply radicals is finding the multipls of the factor and taking out any pairs of numbers outside of the radical.
Example:

     The radical 52 has the factors of 2x2x13 which equal 52. Since 2 has a pair of 2 which makes 4, you bring the 2^2 out of the radical and leave 13 inside the radical. Since the square root of 2 is 2, you take out the power of 2 and leave it as is for the final answer.
