Answer 1

Answer:

$\huge{\underline{\textsf{\textbf{~~~Answer}}}}$

$\sf {2}^{ - 3} = \frac{1}{2}x \\ \sf \color{blue}{we \: know \: that \: {n}^{ - m} = \frac{1}{ {n}^{m} }} \\ \sf \frac{1}{2 {}^{3} } = \frac{1}{2}x \\ \\ \sf \: \frac{1}{8} = \frac{1}{2}x \\ \sf \: x = \frac{1}{2} \times \frac{8}{1} \\ \sf x = \frac{1}{ \cancel2} \times \frac{\cancel8}{1} \\ \sf x = \frac{1}{4} \\ \sf \: \color{indigo} \frac{1}{4} \: can \: be \: written \: as \: \frac{1}{ {2}^{2} } \\ \sf x= {2}^{ - 2}$
