Answer:

[tex]2\sqrt{5}[/tex] or 4.472

Step-by-step explanation:

20 is not a perfect square, meaning that no two integers can be multiplied together to get 20. However, we can try to take perfect squares out of the square root.

[tex]\sqrt{20}[/tex] = [tex]\sqrt{4*5}[/tex] = [tex]\sqrt{4} * \sqrt{5}[/tex] = [tex]2\sqrt{5}[/tex]

(Remember that the square root of 4 is 2.)
