For this case we must rationalize the denominator of the following expression:
[tex]\frac {2 \sqrt {10}} {3 \sqrt {11}} =[/tex]
To rationalize the denominator, that is, remove the root of the denominator, we must multiply by:
[tex]\frac {\sqrt {11}} {\sqrt {11}}[/tex]
So, we have:
[tex]\frac {2 \sqrt {10}} {3 \sqrt {11}} * \frac {\sqrt {11}} {\sqrt {11}} =\\\frac {2 \sqrt {10} * \sqrt {11}} {3 (\sqrt {11}) ^ 2} =\\\frac {2 \sqrt {110}} {3 * 11} =\\\frac {2 \sqrt {110}} {33}[/tex]
Answer:
Option B
