${4}^{-} 8$

#### Explanation:

To the power means relates to the exponents. So for example,

In your question 4 to the power of 2 is ${4}^{2}$
and 4 to the power of 10 is ${4}^{10}$

So to divide, it is ${4}^{2} / {4}^{10}$

Following the exponent rules that you learned, we subtract the indexes (since they have the same base)

${4}^{2 - 10} = {4}^{-} 8$ So the answer is 4 to the power of negative 8.

Not sure why you did 10-8, but I think you had the right idea. You just subtracted the exponents wrong.
