Write down the following as sum of odd numbers 7² and 9²?
Sum of Odd Numbers 7² and 9²
To find the sum of odd numbers 7² and 9², we first need to calculate the square of each number.
Calculating the squares:
- 7² = 7 * 7 = 49
- 9² = 9 * 9 = 81
Now that we have the squares of the numbers, we can proceed to find their sum.
Finding the sum:
To find the sum of odd numbers, we need to add the individual numbers together. In this case, we have two odd numbers, so we will add them together.
Adding the odd numbers:
- 49 + 81 = 130
Therefore, the sum of odd numbers 7² and 9² is 130.
Explanation:
- The given question asks us to find the sum of odd numbers 7² and 9².
- We start by calculating the square of each number. The square of a number is obtained by multiplying the number by itself.
- The square of 7 is obtained by multiplying 7 by 7, resulting in 49.
- Similarly, the square of 9 is obtained by multiplying 9 by 9, resulting in 81.
- Once we have the squares of the numbers, we can proceed to find their sum.
- To find the sum of odd numbers, we simply add the individual numbers together.
- In this case, we have two odd numbers, 49 and 81.
- Adding these two numbers together gives us a sum of 130.
- Therefore, the sum of odd numbers 7² and 9² is 130.
Sum of Odd Numbers 7² and 9²: 130.
Write down the following as sum of odd numbers 7² and 9²?
7² = 1 + 3 + 5 + 7 + 9 + 11 + 13
9² = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17
