Simplify the expression \frac{1}{\sqrt{36}} - \sqrt{27} - \frac{1}{\sqrt{27}} - \sqrt{18} + \frac{1}{\sqrt{18}} - \sqrt{9}
We simplify the expression by simplifying each radical term separately. [ 1√36−√27−1√27−√18+1√18−√9=16−3√3−13√3−3√2+13√2−3 =16−3(√3+√2)+13(1√3+1√2)−3 =16−3(√3+√2)+13(√2+√3√2√3)−3 =16−3(√3+√2)+√2+√33−3 =16+√2+√33−3−3(√3+√2) =16+√2+√33−6(√3+√2) ]
