Q.4
Rationalize the denominator:
1/V6 + V5 - V11
​

Answer 1

$\frac{1}{6v} + 5v - 11v = 0 \\ = > \frac{1 + 30v {}^{2} - 66v {}^{2} }{6v} = 0 \\ = > \frac{1 - 36v {}^{2} }{6v} = 0\\ = > 1 - 36v {}^{2} \\ = > v {}^{2} = \frac{1}{36} \\ = > v = \sqrt{ \frac{1}{36} } \\ = > v = \frac{1}{6}$

I hope that helps you
