Question

Which expressions equivalent to 3^-8/3^-4 ?

Answer 1

Explanation:

When dividing two bases of the same value, keep the base the same, and then subtract the exponent values.

In this case, both bases are 3, which means they stay the same. Then, subtract the exponent values.

`3^(-8-(-4))`

`3^(-8+4)`

`3^(-4)`

`(1)/(3^4)}`

`(1)/(81)`
