Question

What is `8^11 -: 8^7`?

Answer 1

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

Answer 2

`8^4`

Explanation:

Given `8^11-:8^7`

`=8^11/8^7`

Apply the rule that states that `a^b/a^c=a^(b-c)`.

`:.=8^(11-7)`

`=8^4`
