A perfect number is equal to the sum of its proper positive divisors.
A mirror perfect number is equal to the sum of its proper positive divisors when they are read backwards.
From a paper by Joseph L. Pe which is available on the 'net:
10311 = 1 + 3 + 7 + 21 + 491 + 1473 + 3437
7343 + 3741 + 194 + 12 + 7 + 3 + 1 = 11301
10311 is perfect and mirror perfect.
The sum of the 1st perfect number and 2nd perfect number is. . . 34!
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
32 is not Perfect.
73 is not a Perfect number.
A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496
In a theoretical perfect mirror, a mirror is whatever color the object it is reflecting is. However, there are no perfect mirrors. If you look at a mirror tunnel, you can see mirrors are actually GREEN!
I am going to say the image is not perfect for it is a an image, be not deceived by the reflection in a mirror, a true likeness though in reverse.JWP
yes but don't spit
There is no continent that is a perfect mirror image of itself or of any other continent.
Ask your mom.
The sum of the 1st perfect number and 2nd perfect number is. . . 34!
Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
496 is the third perfect number and 8128 is the fourth perfect number.
There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.
A mirror has an infinite number of poles due to its smooth and continuous reflective surface. The pole of a mirror is the point where the normal to the mirror surface intersects it, and this point can be anywhere on the mirror surface.
Yes it is. 6 is the first perfect number, 28 is the second perfect number.
