3. Express 56 as the sum of two odd primes.
Answers
Step-by-step explanation:
56 = 28 + 28
56 as the sum of two odd primes => (28-15)+(28 +15)=13 + 43
Answer:
The Sum of Two Odd primes is (3,53), (13,43), (19,37)
Step-by-step explanation:
Step 1:- We have to write all prime numbers between 1 and 36,
Prime numbers – 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53
Step 2:- Next we have to make sum of two prime numbers equal to 56.
Step 3:- 56-3=53, is a prime number
So the First Pair is (3,53)
Step 4:- 56-5=51, is not a prime number
Step 5:- 56-7= 49, is not a prime number
Step 6:- 56-11= 45, is not a prime number
Step 7:- 56-13= 43, is a prime number
So the Second Pair is (13,43)
Step 8:- 56-17= 39, is not a prime number
Step 9:- 56-19= 37, is a prime number
So the Third Pair is (19,37)
Step 10:- 56-23= 33, is not a prime number
Step 11:- 56-29= 27, is not a prime number
Step 12:- 56-31= 25 , is not a prime number
Step 13:- 56-41= 15, is not a prime number
Step 14:- 56-47= 9, is not a prime number
Therefore, the Sum of two odd primes is (3,53), (13,43), (19,37)
From this Method not only all basic concept of primes numbers and primes number get's cleared and our basic method for finding this also get's improves
