1) \((x - \frac{1}{2})^3 = -8\)
2) \((x - \frac{1}{2})^3 = \frac{27}{8}\)
3) \((x - \frac{1}{3})^3 = -\frac{8}{27}\)
4) \((x - \frac{1}{3})^3 = \frac{8}{27}\)
5) \((x - \frac{5}{2})^3 = -\frac{1}{8}\)
6) \((x - \frac{1}{8})^3 = -\frac{8}{125}\)
7) \((x + \frac{1}{2})^2 = \frac{1}{16}\)
8) \((x - \frac{3}{2})^2 = \frac{9}{16}\)
9) \((x - \frac{5}{6})^2 = \frac{1}{36}\)
10) \((x + \frac{2}{5})^2 = \frac{9}{16}\)
11) \((x + \frac{1}{12})^2 = \frac{16}{9}\)
12) \((x - \frac{4}{7})^2 = \frac{1}{49}\)
