Given, $p = \lim_{x \to 0} {(\frac{\tan x}{x})}^{\frac{1}{x^{2}}}$

$\Rightarrow p = e^{\lim_{x \to 0} (\frac{\tan x - x}{x^{3}})}$

$= e^{\lim_{x \to 0} (\frac{x + \frac{x^{3}}{3} + \frac{2 x^{5}}{5} + . . . - x}{x^{3}})}$

$[∵ For 1^{\infty} form limits, \lim_{x \to a} f {(x)}^{g (x)} = e^{\lim_{x \to a} (f (x) - 1) g (x)}]$

$= e^{1 / 3}$

$∴ 96 \log_{e} p = 96 \times \frac{1}{3} = 32$
