Simplify \(2-9\) to \(-7\).
\[4\times -2{}^{-7}\]
Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[4\times -2\times \frac{1}{{}^{7}}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{4\times -2\times 1}{{}^{7}}\]
Simplify \(4\times -2\) to \(-8\).
\[\frac{-8\times 1}{{}^{7}}\]
Simplify \(-8\times 1\) to \(-8\).
\[\frac{-8}{{}^{7}}\]
Move the negative sign to the left.
\[-\frac{8}{{}^{7}}\]
Simplify \(\frac{8}{{}^{7}}\) to \(\frac{8}{{}^{6}}\).
\[-\frac{8}{{}^{6}}\]
-8/^6
