I am having some trouble with square roots. I have been trying lots to solve these problems, but I just can't get it!!! Thanks for any help anyone can provide!
Here are the questions:
1. (square root of 2 - square root of three)
2. (3 square root of five - 2 square root of three) x (3 square root of five - 2 square root of three)
3. Write the least and the greatest in this set of numbers.
5 square root of 7
3 square root of 7
4 square root of 7
square root of 7
6 square root of 7
Any help is truly appreciated!!! Thank you!!! 
+9675 First question:
√2−√3=2−3√2+√3=−1√2+√3I think your teacher wants you to do this.
Second question:
(3√5−2√3)(3√5−2√3)=45−12√15+12=57−12√15
Third: Greatest = 6sqrt7, Least = sqrt7
Reason: It is because sqrt7 is a positive number. If you use a greater positive number to multiply it, the product would be greater. Therefore 6sqrt7 is the greatest and sqrt7 is the least.
