[tex] \frac{22}{1 + 2 \sqrt{3} } \\ = \frac{22}{1 + 2 \sqrt{3} } \times \frac{1 - 2 \sqrt{3} }{1 - 2 \sqrt{3} } \\ = \frac{22(1 - 2 \sqrt{3} )}{1 - 4.3} \\ = \frac{22(1 - 2 \sqrt{3}) }{1 - 12} \\ = \frac{22(1 - 2 \sqrt{3} )}{ - 11} \\ = - 2(1 - 2 \sqrt{3} ) \\
= - 2 + 4 \sqrt{3} \\
= 4 \sqrt{3} - 2[/tex]

22/(1 + 2V3)

= 22/(1 + 2V3) × (1 - 2V3)/(1 - 2V3)

= 22(1 - 2V3)/(1 - 2V3)(1 + 2V3)

= (22 - 44V3)/(1 - 12)

= (22 - 44V3)/(-11)

= -2 + 4V3

= 4V3 - 2
