Answer 2

a.

[tex] {7}^{ - 4} = [/tex]

[tex] \frac{1}{ {7}^{4} } = [/tex]

[tex] \frac{1}{2401} [/tex]

b.

[tex] {3}^{ - 5} = [/tex]

[tex] \frac{1}{ {3}^{5} } = [/tex]

[tex] \frac{1}{243} [/tex]

c.

[tex] {4}^{ - 2} + {2}^{ - 6} = [/tex]

[tex] \frac{1}{ {4}^{2} } + \frac{1}{ {2}^{6} } = [/tex]

[tex] \frac{1}{16} + \frac{1}{64} = [/tex]

[tex] \frac{4}{ 64} + \frac{1}{64} = [/tex]

[tex] \frac{5}{64} [/tex]

d.

[tex] {3}^{ - 5} + {6}^{ - 3} = [/tex]

[tex] \frac{1}{ {3}^{5} } + \frac{1}{ {6}^{3} } = [/tex]

[tex] \frac{1}{243 } + \frac{1}{216} = [/tex]

[tex] \frac{8}{1944} + \frac{9}{1944} = [/tex]

[tex] \frac{17}{1944} [/tex]
