Thank you so much! This is better than those 5 mins videos. I have my math exam in two days and this was a great refresher!

[@dylanrupnow1654]

can't you just go 5/3. Because root9=3

[@lisagood2523]

wouldnt the denominator be 3 ??

[@baraaali4147]

Lisa Good it wouldn't be 3 bc 9*9=81. The square root of that is 9. If you can't simplify both the top and bottom number, then you don't simplify at all.
