Answer:
The answer to your question is [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Here, there is a difference of squares, so just solve it and simplify
[tex]( 1 + \frac{1}{\sqrt{3} } ) (1 - \frac{1}{\sqrt{3} } )[/tex]
Multiply the binomials
= 1 - [tex]\frac{1}{3}[/tex]
Simplify
= [tex]\frac{3 - 1}{3}[/tex]
= [tex]\frac{2}{3}[/tex]
