Answer 1

Answer:

${( \frac{x}{4} )}^{3} - ({ \frac{4}{x} )}^{3} = {( \frac{x}{4} - \frac{4}{x} ) }^{3} + 3( \frac{4}{x} )( \frac{x}{4} )( \frac{x}{4} - \frac{4}{x} ) \\ \\ = ( \frac{x}{4} - \frac{4}{x} )( ({ \frac{x}{4} - \frac{4}{x}) }^{2} + 3) \\ \\ = ( \frac{x}{4} - \frac{4}{x} )( \frac{ {x}^{2} }{16} + \frac{16}{ {x}^{2} } + 1)$
