Answer 1

a)

${7}^{ - 2} = \frac{1}{ {7}^{2} } = \frac{1}{49}$

b)

${8}^{ - 3} = \frac{1}{ {8}^{3} } = \frac{1}{512}$

c)

${10}^{ - 1} = \frac{1}{10}$

d)

${6}^{ - 3} = \frac{1}{ {6}^{3} } = \frac{1}{216}$

e)

${(24)}^{ - 4} = \frac{1}{ {24}^{4} } = \frac{1}{331 \: 776}$

f)

${(34)}^{ - 3} = \frac{1}{ {34}^{3} } = \frac{1}{39 \: 304}$

g)

${(15)}^{ - 5} = \frac{1}{ {15}^{5} } = \frac{1}{759 \: 375}$

h)

${(97)}^{ - 3} = \frac{1}{ {97}^{3} } = \frac{1}{912 \: 673}$

i)

${(1517)}^{ - 2} = \frac{1}{ {1517}^{2} } = \frac{1}{2 \: 301 \: 289}$
