In class this week we learned how to changed a mix radical into an entire radical. We used this a lot in class this week.

1.) You take your coefficient which in this case is 3 and than you times it by itself how many times the index is. So 3×3= 9

2.) You multiply the number you just got with the radican, 9×9= 81

3.) so my final answer is \sqrt{81}
