Here is the picture it says xxxxxxxxxxxxxxxxxxx

Answer 1

Explanation:

given: 5^3/5^7

= 1/5^(7-3)

= 1/5^4

= 1/625

final answer: 1/625

Answer 2

`5^(-4)`

Explanation:

using the rules of exponents

•
`(a^(m) )/(a^(n) )` =
`a^((m-n))`

•
`a^(-m)` =
`(1)/(a^(m) )`

given

`(5^(3) )/(5^(7) )`

=
`5^((3-7))`

=
`5^(-4)`

=
`(1)/(5^(4) )` ← if required with a positive exponent
