Answer:

Step-by-step explanation:

द्विपद प्रमेय के प्रयोग से

(\frac{2}{x} - \frac{x}{2})^{5} = (\frac{2}{x})^{5} + 5C_{1} (\frac{2}{x})^{4} (-\frac{x}{2}) + 5C_{2} (\frac{2}{x})^{3} (-\frac{x}{2})^{2} + 5C_{3} (\frac{2}{x})^{2} (-\frac{x}{2})^{3} + 5C_{4} (\frac{2}{x})^{1} (-\frac{x}{2})^{4} + (\frac{x}{2})^{5}

  = \frac{32}{x^{5} } + 5 . \frac{16}{x^{4} } (-\frac{x}{2}) + 10 . \frac{8}{x^{3} } . \frac{x^{2}}{4} + 10 . \frac{4}{x^{2} } (-\frac{x^{3}}{8} ) + 5 . \frac{2}{x} (\frac{x^{4} }{16} ) + (-\frac{x^{5} }{32} )

    = \frac{32}{x^{5} } - \frac{40}{x^{3} } + \frac{20}{x} - 5x + \frac{5}{8} . x^{3} - \frac{x^{5}}{32}
