5+10335 + \frac{10}{3}\sqrt{3}

Step-by-step solution

2 steps

Q8 (continued from previous response):

=2(3−3)32−(3)2=6−239−3=6−236= \frac{2(3-\sqrt{3})}{3^2 - (\sqrt{3})^2} = \frac{6-2\sqrt{3}}{9-3} = \frac{6-2\sqrt{3}}{6}

Simplify the second term:

=66−236=1−33= \frac{6}{6} - \frac{2\sqrt{3}}{6} = 1 - \frac{\sqrt{3}}{3}
  1. Subtract the simplified second term from the simplified first term.

    The first term was found in Step 1 to be 6+336+3\sqrt{3}.

    (6+33)−(1−33)(6+3\sqrt{3}) - \left(1 - \frac{\sqrt{3}}{3}\right) =6+33−1+33= 6+3\sqrt{3} - 1 + \frac{\sqrt{3}}{3}
  2. Combine the rational and irrational parts.

    =(6−1)+(33+33)= (6-1) + \left(3\sqrt{3} + \frac{\sqrt{3}}{3}\right) =5+(933+33)= 5 + \left(\frac{9\sqrt{3}}{3} + \frac{\sqrt{3}}{3}\right) =5+1033= 5 + \frac{10\sqrt{3}}{3}

    The expression in the form m+n3m+n\sqrt{3} is 5+1033\boxed{5 + \frac{10}{3}\sqrt{3}}.
