HOW MANY NUMBERS LIE BETWEEN THE SQUARES OF THE FOLLOWING NUMBERS :(i)...
Understanding the Problem
To find how many numbers lie between the squares of two consecutive integers, we need to calculate the square of each number and then determine the numbers that fall in between.
Calculations for Each Case
1. Between 12 and 13:
- Square of 12: 12 * 12 = 144
- Square of 13: 13 * 13 = 169
- Numbers between 144 and 169:
- The numbers are: 145, 146, 147, ..., 168.
- Total count: 169 - 144 - 1 = 24.
2. Between 25 and 26:
- Square of 25: 25 * 25 = 625
- Square of 26: 26 * 26 = 676
- Numbers between 625 and 676:
- The numbers are: 626, 627, 628, ..., 675.
- Total count: 676 - 625 - 1 = 50.
3. Between 99 and 100:
- Square of 99: 99 * 99 = 9801
- Square of 100: 100 * 100 = 10000
- Numbers between 9801 and 10000:
- The numbers are: 9802, 9803, ..., 9999.
- Total count: 10000 - 9801 - 1 = 198.
Summary of Results
- Numbers between 12 and 13: 24
- Numbers between 25 and 26: 50
- Numbers between 99 and 100: 198
Conclusion
By calculating the squares of consecutive integers and finding the range between them, we can easily determine the total numbers that exist in that range. Each case illustrates a clear method to arrive at the answer.
