the simplified expression is 1/9

Step-by-step explanation:

The given expression is $\frac{3^{-6}}{3^{-4}}$

We can apply the exponent law: $\frac{x^a}{x^b}=a^{a-b}$

Applying this law, we get

$\frac{3^{-6}}{3^{-4}}\\\\=3^{-6+4}\\\\=3^{-2}$

Now, apply the exponent rule: $x^{-a}=\frac{1}{x^a}$

$3^{-2}=\frac{1}{3^2}\\\\=\frac{1}{9}$

Hence, the simplified expression is 1/9

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
