3 √ 28 = ( 3 * 2 ) √ 7 = 6 √ 7
1/2 √ 80 = ( 1/2 ) * 4 √ 5 = 2 √ 5
( √ 500 ) / 5 = 1/5 √ 500 = 1/5 √ ( 25 * 4 * 5 ) = ( 1/5 )*5 * 2 √ 5 = 2 √ 5

2 √ 7 = √28
3 √1/3 = √ 3
- ( 4/5 ) √ 75 = - √ ( 16/25 ) * 75 = - √ 48
-----------------------------------------
3 √ 3 = √ 27
2 √ 7 = √ 28
27 < 28
3 √ 3 < 2 √ 7
-------------------------------------------
2/3 √ 72 = √ ( 4/9 ) * 72 = √ 32
7 √ 2/3 = √ 49 * ( 2/3 ) = √ 98/3 = √ 32 ( 2/3 )
32 < 32 ( 2/3 )
2/3 √ 72 < 7 √ 2/3
