$4 {}^{ - 3} = \frac{1}{4 {}^{3} } = \frac{1}{64} \\ </p><p>54 \times 3 {}^{ - 3} =54 \times \frac{1}{ {3}^{3} } = 54 \times \frac{1}{27} = \frac{54}{27} = 2 \\ </p><p>{a}^{ - 3} a {}^{ - 2} a {}^{8} = a {}^{8 - 3 - 2} = a {}^{8 - 5} = a {^3} \\ </p><p>( {a}^{3} ) {}^{ - 6} = a {}^{3 \times ( - 6)} = a {}^{ - 18} \\ </p><p>\frac{b {}^{3} }{b {}^{ - 4} } = b {}^{3 - ( - 4)} = b {}^{3 + 4} = b {}^{7}$
