2. Unlocking the Mystery: How to Find the Square Root of 157
To find the square root of 157, we need to use a method called long division. This method involves breaking down the number into its prime factors and grouping them in pairs. We can then divide the number by the pair and add it to the result.
Step 1: Find the prime factors of 157.
To do this, we can start by dividing the number by the smallest prime number, which is 2. We get 78.5, which is not a whole number. Next, we try dividing it by 3. We get 52.3, which is also not a whole number. We repeat this process for all prime numbers until we get a whole number. We find that 157 is a prime number and cannot be expressed as a product of other prime numbers.
Step 2: Group the prime factors in pairs.
Since 157 is a prime number, we can group it with 1. We get (157, 1).
Step 3: Divide the number by the pair and add it to the result.
We start with the first pair, which is (1,5). We divide 157 by 15 and get 10 as the quotient. We add 15 to the result and get 15.
Next, we bring down the next pair, which is (7, 6). We multiply the result (15) by 2 to get 30. We then find the largest number that can be multiplied by 30 to get a product less than or equal to 176, which is the number formed by the pair (76). We find that 5×30 = 150 is the largest product, which is less than or equal to 176. We subtract 150 from 176 to get 26, which is the remainder.
We then bring down the next pair, which is (0,0) since we have reached the end of the number. We write the remainder (26) as a decimal and bring down two zeros. We get 2600. We also add 5 to the result we have so far to get 20.
Finally, we bring down the next pair, which is (0,1). We multiply the current result (20) by 2 to get 40. We then find the largest number that can be multiplied by 40 to get a product less than or equal to 2601, which is the number formed by the pair (1). We find that 6×40 = 240 is the largest product, which is less than or equal to 2601. We subtract 240 from 2601 to get 261 as the remainder.
We then add a decimal and bring down two zeros. We get 26100. We then find the next pair, which is (0,0). We add a decimal to the result we have so far, and we have the square root of 157 as 12.52996409.
In conclusion, finding the square root of 157 involves breaking down the number into its prime factors, grouping them in pairs, and using long division to find the square root. We can use this method to find the square root of other numbers as well, making it a valuable skill to have.
