Answer:
14.
Step-by-step explanation:
Given that:
[tex]x = 7 – 4 \sqrt{3} [/tex]
To find:
[tex]the \: value \: of \: (x + \frac{1}{x}) \\ [/tex]
Solution:
[tex]x + \frac{1}{x} = (7 – 4 \sqrt{3} ) + \frac{1}{7 – 4 \sqrt{3} } \\ [/tex]
= $\frac{{\mathrm{(}}\mathrm{{-}}{4}\sqrt{3}{\mathrm{)}}^{2}\mathrm{{+}}{1}}{{7}\mathrm{{-}}{4}\sqrt{3}}$
= $\frac{{\mathrm{49}}\mathrm{{-}}{\mathrm{56}}\sqrt{3}\mathrm{{+}}{\mathrm{48}}\mathrm{{+}}{1}}{{7}\mathrm{{-}}{4}\sqrt{3}}$
= $\frac{{\mathrm{98}}\mathrm{{-}}{\mathrm{56}}\sqrt{3}}{{7}\mathrm{{-}}{4}\sqrt{3}}$
= 14 Ans.
