Question

A number to the 8th power divided by the same number to the 5th power equals 27. What is the number?

Answer 1

3

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!

Answer 2

x^8/x^5=27

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