Answer 1

`(b^(4) )/(a)`

Explanation:

`(a^(3)b^(5) )/(a^(4)b )` is the equation we need to simplify. In order to do this, we must remember what these exponents mean.

`(a^(3)b^(5) )/(a^(4)b )` =
`(aaabbbbb)/(aaaab)`

Now, we see that we can divide and cancel.

`(aaabbbbb)/(aaaab)` =
`(bbbb)/(a)` =
`(b^(4) )/(a)`

Another way we can solve this is by knowing that exponents in the denominator become negative when we move them to the numerator:

`(a^(3)b^(5) )/(a^(4)b )` =
`a^(3)b^(5)a^(-4)b^(-1)` =
`a^(-1)b^(4)` =
`(b^4)/(a)`
