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

- which is the answer to the question! (three to the power of 4)
Answer:
A. -34.5>x
Step-by-step explanation:
The area is shaded below -34.5, so we know that x has to be less
The total tiles on stage 25 is 51 tiles.
.....because there is 25 stages on each side so u add 25 and 25 witch makes 50 then u add 1 witch is for the one as the vertex witch makes 51.
