Question : If $\mathrm{p}=7+4 \sqrt{3}$, then what is the value of $\frac{\mathrm{p}^6+\mathrm{p}^4+\mathrm{p}^2+1}{\mathrm{p}^3}$?
Option 1: 2617
Option 2: 2167
Option 3: 2716
Option 4: 2176
Correct Answer: 2716
Solution : Given, $p=7+4\sqrt3$ ⇒ $\frac1p=\frac{1}{7+4\sqrt3}$ ⇒ $\frac1p=\frac{1}{7+4\sqrt3}\times\frac{7-4\sqrt3}{7-4\sqrt3}$ ⇒ $\frac{1}{p}=\frac{7-4\sqrt3}{(7+4\sqrt3)(7-4\sqrt3)}$ We know $(a+b)(a-b)=a^2-b^2$ ⇒ $\frac1p=\frac{7-4\sqrt3}{7^2-(4\sqrt3)^2}$ ⇒ $\frac1p=\frac{7-4\sqrt3}{49-48}$ ⇒ $\frac1p=7-4\sqrt3$ ⇒ $p+\frac1p=7+4\sqrt3+7-4\sqrt3=14$ Now, consider $\frac{p^6+p^4+p^2+1}{p^3}$ $=\frac{p^6+1}{p^3}+\frac{p^4+p^2}{p^3}$ $=(p^3+\frac{1}{p^3})+(p+\frac{1}{p})$ We know, $(a+b)^3=a^3+b^3+3ab(a+b)$ So, $=(p^3+\frac{1}{p^3})+(p+\frac{1}{p})=(p+\frac1p)^3-3(p+\frac{1}{p})+(p+\frac1p)$ $=(p+\frac1p)^3-2(p+\frac{1}{p})$ $=14^3-2\times14$ $=2744-28$ $=2716$ Hence, the correct answer is 2716.
