Pg 214 square roots "simpilfying radicals"

-we learned what how to figure out the biggest perfect square factor of a non perfect square such as 72?
-we also used similar laws when doing it for the biggest perfect cube factor of a number given as an example
-we also simplified a fourth root radical

Today we simplified a squared number by factorizing it pulling off the smallest factor able to such as 2 or 3.
