Simplify:
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?

  • Algebra -

    I think you have the right answer and it matches #4

    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)
