1)`\sqrt(3+2\sqrt2)=\sqrt(2+2\sqrt2+1)=\sqrt((\sqrt2+1)^2)=|\sqrt2+1|=\sqrt2+1`

2)`\sqrt(3-2\sqrt2)=\sqrt(2-2\sqrt2+1)=\sqrt((\sqrt2-1)^2)=|\sqrt2-1|=\sqrt2-1`

3)`\sqrt(8-2\sqrt15)=\sqrt(5-2\sqrt15+3)=\sqrt((\sqrt5-\sqrt3)^2)=|\sqrt5-\sqrt3|=\sqrt5-\sqrt3`

4)`\sqrt(8+2\sqrt15)=\sqrt(5+2\sqrt15+3)=\sqrt((\sqrt5+\sqrt3)^2)=|\sqrt5+\sqrt3|=\sqrt5+\sqrt3`

5)`\sqrt(5-2\sqrt6)=\sqrt(3-2\sqrt6+2)=\sqrt((\sqrt3-\sqrt2)^2)=|\sqrt3-\sqrt2|=\sqrt3-\sqrt2`

6)`\sqrt(5+2\sqrt6)=\sqrt(3+2\sqrt6+2)=\sqrt((\sqrt3+\sqrt2)^2)=|\sqrt3+\sqrt2|=\sqrt3+\sqrt2`

7)`\sqrt(4+2\sqrt3)=\sqrt(3+2\sqrt3+1)=\sqrt((\sqrt3+1)^2)=|\sqrt3+1|=\sqrt3+1`

8)`\sqrt(4-2\sqrt3)=\sqrt(3-2\sqrt3+1)=\sqrt((\sqrt3-1)^2)=|\sqrt3-1|=\sqrt3-1`
