4^-8

Explanation:

To the power means relates to the exponents. So for example, www.liverpool.ac.ukwww.liverpool.ac.uk

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.
