Solution steps

7^{- 5} \cdot 4^{- 5}

7^{- 5} = \frac{1}{16807}

= \frac{1}{16807} \cdot 4^{- 5}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

4^{- 5} = \frac{1}{4 ^{5}}

= \frac{1}{16807} \cdot \frac{1}{4 ^{5}}

4^{5} = 1024

= \frac{1}{16807} \cdot \frac{1}{1024}

\frac{1}{16807} \cdot \frac{1}{1024} = \frac{1}{17210368}

= \frac{1}{17210368}
