Determine the number of odd binomial coefficients in the expansion
... Determine the number of odd binomial coefficients in the expansion of (x + y)1000 . Theorem 0.1. The number of odd entries in row n of Pascal’s Triangle is 2 raised to the number of 1’s in the binary expansion of n. Proof. The binomial theorem says that n µ ¶ X n n−k k n (a + b) = a b . k k=0 So wit ...

On Existence of Infinitely Many Primes of The Form x2+1
... It is well known that there are infinitely many prime factors of Fermat numbers, because prime factor of a Fermat prime is the Fermat prime itself but a composite Fermat number has at least two prime factors and Fermat numbers are pairwise relatively prime. Hence we conjecture that there is at least ...

UNIT 3: DIVISIBILITY 1. Prime numbers
... Here are some quick and easy checks to see if one number will divide exactly. Divisible by 2. A number is divisible by 2 if the last digit is 0, 2, 4, 6 or 8. Example: 2346 is divisible by 2 since the last digit is 6. Divisible by 3. A number is divisible by 3 if the sum of the digits is divisible b ...
