What is the next number in the sequence 25 36 49 64?
81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.
What do you call the squares of whole numbers?
The squares of whole numbers are called perfect squares. A perfect square is a number that can be expressed as the product of an integer multiplied by itself. For example, 1, 4, 9, 16, and 25 are perfect squares because they can be written as 1^2, 2^2, 3^2, 4^2, and 5^2, respectively.
What do numbers 25 16 and 9 have in common?
The numbers 25, 16, and 9 are all perfect squares. A perfect square is a number that can be expressed as the product of an integer with itself. In this case, 25 is 5^2, 16 is 4^2, and 9 is 3^2.
What is the smallest negative perfect square that is divisible by the four smallest prime numbers?
Perfect squares are positive. A smallest negative number doesn't exist. The four smallest prime numbers are 2, 3, 5 and 7. The smallest perfect square would have to be 2^2 x 3^2 x 5^2 x 7^2 or 44,100
What 2 numbers have 5 as their GCF?
5 and 10 or 5 and any multiple of 5 for a start
What numbers have 2 and 5 in their prime factorization?
Since the number 10 has the prime factorization of 2 x 5, any multiple of 10 has the numbers 2 and 5 in their prime factorization.
What are 2 almost perfect numbers between 5 and 20?
Perfect numbers are numbers where all the factors add to that number. For example 6's factors are 1,2, and 3 and 1+2+3=6. Therefore the next perfect number isn't until 28 which is 1,2, 4, 7, 14 where 1+2+4+7+14= 28 An almost perfect number is a number which, when adding all of its proper divisors (all divisors except himself), gives you one less, or one more then the number itlself. Up to now all known almost perfect numbers are 2^n. So to answer your question, the 2 almost perfect numbers between 5 and 20 are 8 and 16. Divisors of 8: 1,2,4 -----> 1+2+4=7 Divisors of 16: 1,2,4,8 -----> 1+2+4+8=15
How are irrational numbers different from other numbers?
A rational number can be expressed as a fraction, with whole numbers in the numerator and the denominator, for example 2/3, -3/4, or 5 (which is equal to 5/1). An irrational number can not be expressed as such a fraction. For example, the square root of 2, the square root of any positive integer that is not a perfect square, pi, the number e.
Which one of the numbers does not belong in the following series 5-2-8-13-16?
It could be any one of them. 5: The smallest prime number with a composite on either side. 2: The only even prime number. 8: The only perfect cube number. 13: The only 2-digit prime. 16: The only perfect square number.
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}.
