7^{3} (\frac{1}{7})^{5}

7^{3} = 343

= 343 (\frac{1}{7})^{5}

Wende Exponentenregel an:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

(\frac{1}{7})^{5} = \frac{1 ^{5}}{7 ^{5}}

= 343 \cdot \frac{1 ^{5}}{7 ^{5}}

1^{5} = 1

= 343 \cdot \frac{1}{7 ^{5}}

7^{5} = 16807

= 343 \cdot \frac{1}{16807}

343 \cdot \frac{1}{16807} = \frac{1}{49}

= \frac{1}{49}
