To simplify the expression $8^{-2}\cdot a^7$, we need to apply the rule that any number to the power of -n is equal to 1 divided by that number to the power of n.

Step 1: Rewrite $8^{-2}$ as $\frac{1}{8^2}$.

Step 2: Calculate $8^2$ which is 64.

Step 3: Substitute $8^2$ with 64 in the expression, so we get $\frac{1}{64}\cdot a^7$.

So, the simplified expression is $\frac{1}{64}a^7$.
