Simplify the Power Fraction: 7^10 ÷ 9^10

To solve this problem, let's transform the expression $\frac{7^{10}}{9^{10}}$.

• Step 1: Identify the Form

The expression $\frac{7^{10}}{9^{10}}$ fits the pattern $\frac{a^m}{b^m}$.

• Step 2: Apply the Power of a Quotient Rule

The power of a quotient formula is $\frac{a^m}{b^m} = \left(\frac{a}{b}\right)^m$.

Substitute $a = 7$, $b = 9$, and $m = 10$ into this formula, and we have:

$\frac{7^{10}}{9^{10}} = \left(\frac{7}{9}\right)^{10}$.

We can see that this transformation results in the expression $\left(\frac{7}{9}\right)^{10}$, which matches answer choice 1.

Therefore, the final expression is $\left(\frac{7}{9}\right)^{10}$.

Thus, the correct reformulated expression is $\left(\frac{7}{9}\right)^{10}$.
