Express the given numbers as:
the sum of two odd primes:
(i) 50 (ii) 40

Answer

To express the given numbers (50 and 40) as the sum of two odd primes, we can follow these steps:

### Step 1: Identify the odd prime numbers
First, we need to list the odd prime numbers up to 50. The prime numbers are those greater than 1 that have no divisors other than 1 and themselves. The odd prime numbers up to 50 are:
- 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47

### Step 2: Find the sum for 50
Now, we need to find two odd prime numbers from our list that add up to 50. We can do this by checking combinations of the odd primes:
- 47 + 3 = 50

Thus, one way to express 50 as the sum of two odd primes is:
**50 = 47 + 3**

### Step 3: Find the sum for 40
Next, we need to find two odd prime numbers that add up to 40. Again, we will check combinations:
- 37 + 3 = 40

Thus, we can express 40 as:
**40 = 37 + 3**

### Final Answers
- For 50: **50 = 47 + 3**
- For 40: **40 = 37 + 3**
