Calculate (10/13)^8: Evaluating Powers of Fractions

The fraction $\frac{10}{13}$ raised to the power of 8 can be expressed by applying the power to both the numerator and the denominator based on the rule for powers of a fraction:

$\left(\frac{10}{13}\right)^8 = \frac{10^8}{13^8}$

To solve for the given expression, we use the formula $\left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}$. This means that the fraction power rule allows us to take each component of the fraction and raise it to the required power:

• Step 1: Apply the power of 8 to the numerator: $10^8$.
• Step 2: Apply the power of 8 to the denominator: $13^8$.
• Step 3: Combine both into a single fraction: $\frac{10^8}{13^8}$.

Thus, the expression $\left(\frac{10}{13}\right)^8$ simplifies to $\frac{10^8}{13^8}$.

Therefore, the correct answer from the choices provided is $\frac{10^8}{13^8}$, corresponding to choice 3.
