证明过程：
1+1
=4-2
=4-\frac{9}{2}+\frac{9}{2}-2
=\sqrt{(4-\frac{9}{2})^2}+\frac{9}{2}-2
=\sqrt{4^2-2\times 4\times \frac{9}{2}+(\frac{9}{2})^2}+\frac{9}{2}-2
=\sqrt{16-36+(\frac{9}{2})^2}+\frac{9}{2}-2
=\sqrt{-20+(\frac{9}{2})^2}+\frac{9}{2}-2
=\sqrt{25-45+(\frac{9}{2})^2}+\frac{9}{2}-2
=\sqrt{5^2-2\times 5\times \frac{9}{2}+(\frac{9}{2})^2}+\frac{9}{2}-2
=\sqrt{(5-\frac{9}{2})^2}+\frac{9}{2}-2
=5-\frac{9}{2}+\frac{9}{2}-2
=5-2
=3
