Question

Rewrite 81 as 3 to some power.

Answer 1

First, let's find all the factors of 81:

81/3=27
27/3=9
9/3=3
3/1=1

So the factors of 81 are 3,3,3,3, (the numbers by which we divided here).

This means we can write down 81 as 3*3*3*3 or
`3^(4)` - which is the answer to the question! (three to the power of 4)
