Well if you have 30/72 you first need to find the greatest common factor, which happens to be 6. The divide both 30 and 72 by 6 and you get 5/12. This cannot be simplified therefore it is now in simplest form.
√-72 = i√(622) = i6√2
it depends on what surd you have. Take root 72 for example, to simplify this, divide by a factor of 72, in this case 8, so that you are left with root 8 times by root 9. The root 9 can be simplified to just 3, and you will be left with 3 root 8 as your simplified answer

The lowest term of 72 over 192 = 3/8
No.
47/72 is already simplified
132/240 = 11/20
42/132 = 7/22
9/132 = 3/44
It is: 72/96 = 3/4 simplified
-13/72 cannot be simplified.
Yes.
It is: 72/132 = 6/11
72 over 132 in lowest terms is 6/11
72 over 132 reduced to lowest terms is 6/11
55/72
