Evaluate:
[tex] \sf \: a. \: 5 {}^{ - 3} [/tex]
[tex] \sf \: b. \: \frac{1}{ {4}^{ - 2} } [/tex]

Solution:
[tex] \sf \: a. \: {5}^{- 3} = \frac{1}{ {5}^{3} } = \frac{1}{5 \: × \: 5 \: × \: 5} = \frac{1}{125} [/tex]
[tex] \sf \: b. \: \frac{1}{ {4}^{ - 2} } = \frac{1}{ \frac{1}{4 {}^{2} } } = {4}^{2} = 4 \: × \: 4 = 16[/tex]
