If I could have two lives, I would be a researcher first, then a crazy political activist second.

What the future holds for me:

(The left and right extremes are less probable jobs, but perhaps the most interesting.)

← Increasingly scientific | Increasingly political →

Studying Biolinguistics < Molecular Biology researcher < Just a Doctor <|> Passionate Political Activist > (Almost impossible) Prime Minister of Canada

South Park: *****

Family Guy: *****

Simpsons: **** - maybe it's too intellectual for me... I just want a good laugh without the need to think.

Note to self:

Worksheet Question #21:

${\frac {2{\sqrt {7}}+{\sqrt {3}}}{3{\sqrt {7}}-{\sqrt {3}}}}\times {\frac {3{\sqrt {7}}+{\sqrt {3}}}{3{\sqrt {7}}+{\sqrt {3}}}}$

Taking the bottom part first:

$(3{\sqrt {7}}-{\sqrt {3}})(3{\sqrt {7}}+{\sqrt {3}})$

Expand it:

$63+{\sqrt {189}}-{\sqrt {189}}-3=60$

Now the top part:

$(2{\sqrt {7}}+{\sqrt {3}})(3{\sqrt {7}}+{\sqrt {3}})$

Expand it:

${\sqrt {1764}}+{\sqrt {84}}+{\sqrt {189}}+3$

Note:

${\sqrt {84}}+{\sqrt {189}}=2{\sqrt {21}}+3{\sqrt {21}}=5{\sqrt {21}}$

Simply:

$42+5{\sqrt {21}}+3=9+{\sqrt {21}}$

Putting the two parts together, we get: ${\frac {9+{\sqrt {21}}}{60}}$

Multiple Choice Answer: C

You gotta be kidding! The last step (where 5 disappears and 9 appears) makes no sense at all!
