1. Problem Description

The problem is to simplify the expression:
33×(2)+33×(2)+33×1(33)2+(33)2+(33)2×(2)2+(2)2+12\frac{\frac{\sqrt{3}}{3} \times (-2) + \frac{\sqrt{3}}{3} \times (-2) + \frac{\sqrt{3}}{3} \times 1}{\sqrt{(\frac{\sqrt{3}}{3})^2 + (\frac{\sqrt{3}}{3})^2 + (\frac{\sqrt{3}}{3})^2} \times \sqrt{(-2)^2 + (-2)^2 + 1^2}}

2. Solution Steps

First, simplify the numerator:
33×(2)+33×(2)+33×1=33(22+1)=33(3)=3\frac{\sqrt{3}}{3} \times (-2) + \frac{\sqrt{3}}{3} \times (-2) + \frac{\sqrt{3}}{3} \times 1 = \frac{\sqrt{3}}{3}(-2 - 2 + 1) = \frac{\sqrt{3}}{3}(-3) = -\sqrt{3}
Next, simplify the first square root in the denominator:
(33)2+(33)2+(33)2=39+39+39=99=1=1\sqrt{(\frac{\sqrt{3}}{3})^2 + (\frac{\sqrt{3}}{3})^2 + (\frac{\sqrt{3}}{3})^2} = \sqrt{\frac{3}{9} + \frac{3}{9} + \frac{3}{9}} = \sqrt{\frac{9}{9}} = \sqrt{1} = 1
Then, simplify the second square root in the denominator:
(2)2+(2)2+12=4+4+1=9=3\sqrt{(-2)^2 + (-2)^2 + 1^2} = \sqrt{4 + 4 + 1} = \sqrt{9} = 3
Therefore, the denominator is 1×3=31 \times 3 = 3.
The expression becomes:
33\frac{-\sqrt{3}}{3}

3. Final Answer

33-\frac{\sqrt{3}}{3}
