Answer 2

Answer:

8√5

Step-by-step explanation:

split the number into a product pair with one being a perfect square. If you can not find the largest perfect square to begin with, start with a smaller one

√320=√16×20

=√16×√20=2√20

we continue this process until there are no more perfect squares

4√20=4√4×5

=4√4√5

=4×2√5

=8√5
