3 squared divided by the square root of 80.

Multiple choices:

1. square root of 80 divided by 3 to the negative 2nd power

2. 4 over 9 times the square root of 5

3. 5 over 4 times the square root of 5

4. 9 over 20 times the square root of 5

However, I got 9 times the square root of 5 divided by 20. What is going on here?

how about

#4 (9 over 20) times the square root of 5, isn't that what you said?

(9√5)/20 is the same as (9/20)(√5)
