Question

Answer 1

\(=2-\sqrt{3}+\sqrt{3}-1=1\)

Answer 2

\(\sqrt{\left(2-\sqrt{3}\right)^2}+\sqrt{\left(1-\sqrt{3}\right)^2}\)

\(=\left|2-\sqrt{3}\right|+\left|1-\sqrt{3}\right|\)

\(=2-\sqrt{3}+\sqrt{3}-1\)

`=1`

Answer 3

`\sqrt{(2-\sqrt{3})^2}+\sqrt{(1-\sqrt{3})^2}`

`=|2-\sqrt{3}|+|1-\sqrt{3}|`

`=2-\sqrt{3}+\sqrt{3}-1` (Vì `2 > \sqrt{3} > 1`)

`=1`

Answer 4

\(\sqrt{\left(2-\sqrt{3}\right)^2}+\sqrt{\left(1-\sqrt{3}\right)^2}\)

\(=2-\sqrt{3}-1+\sqrt{3}\)

\(=1\)
