Step-by-step explanation:
When dividing two exponents, you can use a formula of:
[tex]\frac{x^a}{x^b} = x^{a - b}[/tex]
So your question would return:
[tex]\frac{3^2}{3^6} = 3^{2-6} = 3^{-4}[/tex]
When an exponent is negative, it is equal to 1 divided by the positive number, so for this question, it would be:
[tex]\frac{1}{3^4}[/tex]
Or in its expanded form:
[tex]\frac{1}{81}[/tex]
Hope this helps!
