So we are given the following equation...
[tex]\sqrt{6} -\sqrt{2}[/tex]
First, we must find the square root of 6!
[tex]\sqrt{6} =2.44948974[/tex]
Next, lets find the square root of 2!
[tex]\sqrt{2} =1.41421356[/tex]
Finally, we must subtract the two to get the final answer!
[tex]2.44948974-1.41421356=1.03527618[/tex]
Round it and your final answer is 1!
