**FAQs:**
**Q: What is a prime number?
**
A: A prime number is a whole number greater than 1 that cannot be formed by multiplying two smaller whole numbers. For example, the first six prime numbers are 2, 3, 5, 7, 11, and 13.
**Q: What do you mean by “square sum” and “cube sum”?
**
A: The square sum of a number is obtained by squaring each digit in the number and then adding the results together. For instance, the square sum of the number 15 is (1^2 + 5^2) 36. The cube sum follows the same concept but raises each digit to the power of three instead. So, the cube sum of the number 15 is (1^3 + 5^3) 128.
**Q: What are the other prime numbers with the same property as 65 and 115?**
A: The only other two pairs of prime numbers whose square and cube sums share this property are {2, 1}, and {17, 37}. These findings were discovered in the late 19th century by mathematicians.
**Q: How do I calculate the percentage of a larger number within a smaller one?**
A: To find the percentage of a larger number within a smaller one, first determine the difference between the two numbers. Then, divide this difference by the smaller number and multiply the result by 100 to obtain the percentage. For example, to calculate the percentage of 75 within 123, follow these steps:
1. Determine the difference: abs(123 – 75) 48
2.
