4096

Explanation:

A number raised to a power of another number means you should multiply the base number the number of times to which it has been raised to. So, in this case, 8 is raised to 11 times in the numerator and 7 times in the denominator. Since we know that the numbers in the numerator and denominator could be canceled, we obtain 8 power 4 which is equal to 4096
