Step-by-Step Solution

We begin by analyzing the given expression: (9×5)12(5×9)6 \frac{\left(9\times5\right)^{12}}{\left(5\times9\right)^6} . Using the property of exponents known as the Power of a Quotient Rule, we can rewrite this expression.
This rule states that aman=amn \frac{a^m}{a^n} = a^{m-n} . Here, both the numerator and the denominator have the same base, 9×59\times5 or equivalently 5×95\times9, therefore we can apply this rule.

Let's apply the Power of a Quotient Rule:

  • Identify the base, which is 9×59\times5.

  • Subtract the exponent in the denominator from the exponent in the numerator: 12612 - 6.

Thus, the expression simplifies to (9×5)126\left(9\times5\right)^{12-6}.

The solution to the question is: (9×5)126\left(9\times5\right)^{12-6}.

Answer

(9×5)126 \left(9\times5\right)^{12-6}
