How do you show 9 as a deficient number?
Deficient number From Wikipedia, the free encyclopediaIn mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including nitself. An equivalent definition is that the sum of all proper divisors of the number (divisors other than the number itself) is less than the number. The value 2n − σ(n) is called the deficiency of n.The first few deficient numbers are: 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21, 22, 23, 25, 26, 27, … (sequence A005100 in OEIS)As an example, consider the number 21. Its divisors are 1, 3, 7 and 21, and their sum is 32. Because 32 is less than 2 × 21, the number 21 is deficient. Its deficiency is 2 × 21 − 32 = 10.An infinite number of both even and odd deficient numbers exist. For example, all odd numbers with one or two distinct prime factors, and all proper divisors of deficient or perfect numbers are deficient.Closely related to deficient numbers are perfect numbers with σ(n) = 2n, and abundant numbers with σ(n) > 2n. The natural numbers were first classified as either deficient, perfect or abundant byNicomachus in his Introductio Arithmetica (circa 100).
Is the number 32 a perfect number?
32 is not Perfect.
Is 32 a perfect number?
No.
Is 32 an abundant number?
No. The proper divisors of 32 are 1, 2, 4, 8, and 16. Their sum, 1 + 2 + 4 + 8 + 16 = 31, which is less than 32, so it is not an abundant number.
Is the square root of 32 a rational number?
No, because 32 is not a perfect square.
Is 1024 an abundant ofr deficient number?
Deficient. The sum of its proper factors is 1+2+4+8+16+32+64+128+256+512 = 1023. Since that sum is less than 1024, it is deficient.
Is 32 a deficient number?
no
What are the Math terms abundant perfect and deficient?
They refer to the sum of a number's proper divisors, defined here as all of the factors except the number itself.a perfect number equals the sum of its proper divisorsa deficient number is greater than the sum of its proper divisorsan abundant number is less than the sum of its proper divisors

Is the number 32 a perfect number?
32 is not Perfect.
Is 64 a deficient number?
32+16+8+4+2+1=63. 64 is deficient.
Is 32 a perfect number?
No.
Is 32 an abundant number?
No. The proper divisors of 32 are 1, 2, 4, 8, and 16. Their sum, 1 + 2 + 4 + 8 + 16 = 31, which is less than 32, so it is not an abundant number.
What number is a perfect square and has a factor of 32?
The number that is a perfect square and has a factor of 32 is 64. A perfect square is a number that can be expressed as the product of an integer multiplied by itself, such as 8 x 8 = 64. Since 32 is a factor of 64, it means that 64 can be divided evenly by 32 without leaving a remainder.
Is the square root of 32 a rational number?
No, because 32 is not a perfect square.
What number is a factor of 32 and is a perfect square and its only prime factorization number is 2?
16 2*16 = 32
Is 32 an almost perfect number?
Yes. The only known almost perfect numbers are the powers of 2. 32 = 2^5 is an almost perfect number. It has not yet been proved whether {x: x = 2^n for n in N} = {x: x is an almost perfect number}.
