Step-by-step solution

To solve this problem, we will employ exponent rules:

  • Convert the negative exponent: (56×9×11)3=(6×9×115)3\left(\frac{5}{6 \times 9 \times 11}\right)^{-3} = \left(\frac{6 \times 9 \times 11}{5}\right)^3.
  • Simplify using the power of a quotient: (6×9×115)3=(6×9×11)353\left(\frac{6 \times 9 \times 11}{5}\right)^3 = \frac{(6 \times 9 \times 11)^3}{5^3}.
  • Further expand separately: 63×93×11353\frac{6^3 \times 9^3 \times 11^3}{5^3}.

Therefore, each proposed expression 63×93×11353\frac{6^3 \times 9^3 \times 11^3}{5^3}, (6×9×11)353\frac{(6 \times 9 \times 11)^3}{5^3}, and (6×9×115)3\left(\frac{6 \times 9 \times 11}{5}\right)^3 are equivalent and correct interpretations of the original expression.
