Explanation:

First let's factor 72:


72 = 2^(3) * 3^(2)

Next, we can try to take the square root of each term in this factorization:


\sqrt{2^(3)}


2√(2)


\sqrt{3^(2)}


3

Finally, we can multiply these two together:


2√(2) * 3


6√(2)

Alternatively, you could find that 72 is
2 * 6^(2) and took the square root of the
6^(2) and moved the 6 out of the square root.
