$${\text{The value of }}\frac{{4 + 3\sqrt 3 }}{{7 + 4\sqrt 3 }}{\text{ is?}}$$
A. 5$$\sqrt 3 $$ - 8
B. 5$$\sqrt 5 $$ + 8
C. 8$$\sqrt 3 $$ + 5
D. 8$$\sqrt 3 $$ - 5
Answer: Option A
Solution (By Examveda Team)
$$\frac{{4 + 3\sqrt 3 }}{{7 + 4\sqrt 3 }}$$(By rationalization of denominator)
$$\eqalign{ & = \frac{{4 + 3\sqrt 3 }}{{7 + 4\sqrt 3 }} \times \frac{{7 - 4\sqrt 3 }}{{7 - 4\sqrt 3 }} \cr & = \frac{{\left( {4 + 3\sqrt 3 } \right)\left( {7 - 4\sqrt 3 } \right)}}{{49 - 48}} \cr} $$
