e) \(\frac{3}{7} - \frac{1}{7}\)^2 \(\cdot\) \(\frac{49}{16}\) + \(\frac{1}{2}\)^3 = \(\frac{2}{7}\)^2 \(\cdot\) \(\frac{49}{16}\) + \(\frac{1}{8}\) = \(\frac{4}{49}\) \(\cdot\) \(\frac{49}{16}\) + \(\frac{1}{8}\) = \(\frac{4}{16}\) + \(\frac{1}{8}\) = \(\frac{1}{4}\) + \(\frac{1}{8}\) = \(\frac{2}{8}\) + \(\frac{1}{8}\) = \(\frac{3}{8}\)
