What is $3^{-4} \cdot 3^{-8} \cdot 3^{14}$?
I notice that all the bases are 3, so I can use the exponent rules to simplify this expression. I recall that when I multiply powers with the same base, I can add the exponents. So I can rewrite this as $3^{(-4) + (-8) + 14}$. Now I just need to evaluate the exponent by adding the numbers. I get $3^{2}$. This is just 9.
