Question

Tính giá trị của biểu thức: 1/2+√3 - 1/2-√3

Answer 1

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

Answer 2

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

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

\(=0+0=0\)

Answer 3

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