Math Problem Statement
Find the square root 59684 using long division method
Solution
To find the square root of using the long division method, follow these steps:
Step 1: Pair the digits from right to left
Divide the number into pairs of two digits starting from the right. Add extra 0s if needed.
Step 2: Find the largest number whose square is less than or equal to the leftmost pair
The leftmost pair is .
- The largest number whose square is less than or equal to is , because:
Write as the first digit of the quotient. Subtract from :
Bring down the next pair , so the new dividend becomes .
Step 3: Double the quotient and determine the next digit
Double the current quotient :
Now, find a digit such that:
- If , , which is less than .
- If , , which exceeds .
Thus, . Add to the quotient and subtract from :
Bring down the next pair , so the new dividend becomes .
Step 4: Repeat the process
Double the current quotient :
Now, find a digit such that:
- If , , which is less than .
- If , , which exceeds .
Thus, . Add to the quotient and subtract from :
Step 5: Continue for more accuracy (optional)
Bring down two zeros () to get . Repeat the process if further decimal places are needed.
Result
The square root of using the long division method is approximately:
