Step-by-Step Solution

To solve this problem, we recognize the application of exponent rules for powers of fractions. The expression 123233\frac{12^3}{23^3} can be rewritten by using the formula ambm=(ab)m\frac{a^m}{b^m} = \left(\frac{a}{b}\right)^m.

Let's apply this to the given problem:

  • Step 1: Identify the structure as ambm\frac{a^m}{b^m}, where a=12a = 12, b=23b = 23, and m=3m = 3.
  • Step 2: Use the formula ambm=(ab)m\frac{a^m}{b^m} = \left(\frac{a}{b}\right)^m to transform 123233\frac{12^3}{23^3} into (1223)3\left(\frac{12}{23}\right)^3.

The expression 123233\frac{12^3}{23^3} simplifies to (1223)3\left(\frac{12}{23}\right)^3.

Therefore, the correct corresponding expression is (1223)3\left(\frac{12}{23}\right)^3.

Answer

(1223)3 \left(\frac{12}{23}\right)^3
