Answer 1

Answer:

6$\sqrt{5}$

Step-by-step explanation:

First, we take out any factors of 180 which are squares.

The square factor 9 is most easily seen.

So, $\sqrt{180} = \sqrt{9 * 20}$ which is equal to $3\sqrt{20}$.

Again, we can take out more factors. Notice that 4 is 2 squared and a factor of 20. So, $3 \sqrt{ 4* 5}$ which is equal to 3 × 2 × $\sqrt{5}$, which is 6$\sqrt{5}$.
