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)
I know this is not an answer but if your having trouble with this there is a website called Desmos all you do is type in the equation for the graph and it gives you the answer
Answer:

Step-by-step explanation:
180-113.4=66.6
Answer:
7.24pm
Step-by-step explanation:
196+50=3.9h
0.9h=0.9x60mnt=54mnt
3.9h=3h 54mnt
3:30pm+3h 54mnt
3:30pm+3h 54mnt=7.2pm
The 2 numbers required are 13*8 and 14 * 8
that is 104 and 117
