    3

    Step-by-step explanation:

    Let's try 4 first.

    4^8 is 65536, and 4^5 is 1024.

    65536 / 1024 is 64, so 4 is not an answer.

    And, let's try 3.

    3^8 is 6561, and 3^5 is 243.

    6561 / 243 is 27, so 3 is the answer!

    x^8/x^5=27

    x=3 when you flip the equation (rounded number)
