Step-by-Step Solution

To solve this problem, we'll employ the exponent rules for fractions:

  • Step 1: Recognize that 29119\frac{2^9}{11^9} follows the general form anbn\frac{a^n}{b^n}.
  • Step 2: Apply the property (ab)n=anbn\left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}.
  • Step 3: Substitute into the property to express the fraction as (211)9\left(\frac{2}{11}\right)^9.

Let's work through the steps in detail:

Step 1: The expression 29119\frac{2^9}{11^9} can be viewed as each number, 2 and 11, raised to the 9th power in a fraction.

Step 2: Utilize the exponent rule (ab)n=anbn\left(\frac{a}{b}\right)^n = \frac{a^n}{b^n} to rewrite the fraction with a single power.

Step 3: Therefore, the expression 29119\frac{2^9}{11^9} simplifies to (211)9\left(\frac{2}{11}\right)^9.

Therefore, the correct answer is indeed (211)9\left(\frac{2}{11}\right)^9.

The correct choice from the provided options is:

(211)9 \left(\frac{2}{11}\right)^9

Answer

(211)9 \left(\frac{2}{11}\right)^9
