Good morning. I have an extra credit assignment for my statistics class in school. The question is: What are two things special about the number 81 that are not true for any other numbers? Any help is appreciated men.

Wow Wikipedia reveals all lol.

I was going to say 81 is a prime number and it is a square of 9 but only the latter applies uniquely.

Are you doing Discrete Maths?

If you cut 81 in half, you will get 01.

* Cincinnati Bengals Bennie Brazell wears #81

 

* Buffalo Bills Peerless Price wears # 81

 

* Dallas Cowboys Terrell Owens wears #81

 

* Denver Broncos Quincy Morgan wears #81

 

* Detroit Lions Dick "Night Train" Lane wore #81

 

* Detroit Lions Calvin Johnson wears #81

 

* New England Patriots Randy Moss wears #81

 

* New York Giants Amani Toomer wears #81

 

* Philadelphia Eagles Jason Avant wears #81

 

* St. Louis Rams Torry Holt wears #81

 

* Arizona Cardinals Anquan Boldin wears #81

 

* Seattle Seahawks Nate Burleson wears #81

 

* Carolina Panthers Sammy Burke wears #81

81

Just turn that in as your report.

 

It's sure to get you top marks. I practically guarantee it.

Just tell them it means jews must die and America must finish what Nazi Germany failed to do.

Eighty-one is the square of 9 and the fourth power of 3. Like all powers of three, 81 is a perfect totient number. It is a heptagonal number and a centered octagonal number. It is also a tribonacci number, and an open meandric number. 81 is the ninth member of the Mian-Chowla sequence.

 

In base 10, it is a Harshad number, and one of three non-trivial numbers (the other two are 1458 and 1729) which, when its digits are added together, produces a sum which, when multiplied by its reversed self, yields the original number:

 

8 + 1 = 9

9 X 9 = 81

 

(although this case is somewhat degenerate, as the sum has only a single digit).

 

 

That's all Wiki had to say about it.

way over your head, huh? Its ok buddy, your minium wage job you cant keep for 3 days will help you one day :gaykeke:

81 (eighty-one) is the natural number following 80 and preceding 82.

 

these are entirely true and the teacher must accept them as it is exactly what he asked for

haha..the responses so far are interesting, but I doubt any will get me extra credit...any other ideas men of myg0t?:gaysex2:
Just go on yahoo answers and post this. I am actually surprised that anyone here actually helped you out (me included).

Thanks for the advice. The answer is the number 81 is the only whose digital root ( 8 + 1 = 9) equals its square root (9 x 9 = 81). /thread

Wrong.
