Answer:
The answer is -6
Explanation:
In order to find this, we first must notice that the number is smaller than the base. This means the answer will be negative.
Next, to find what that negative number is, we need to know what we have to raise the base (2) by to get the denominator (64). We need to raise 2 to the 6th power to get 64.
Therefore, our answer is -6
