The correct Answer is:
To find the square root of 0.2916 using the long division method, we can follow these steps: ### Step 1: Pair the digits Start by pairing the digits of the number from the decimal point. For 0.2916, we can pair them as follows: - (0) (29) (16) ### Step 2: Find the largest square Now, we look for the largest square number that is less than or equal to the first pair (0). The largest square is 0 (since 0² = 0). ### Step 3: Subtract and bring down the next pair Subtract 0 from 0, which gives us 0. Now, bring down the next pair (29) next to it. We now have 0 (from the first pair) and 29. ### Step 4: Double the divisor Double the current result (which is 0). So, 0 × 2 = 0. We will denote this as our new divisor. ### Step 5: Find the next digit Now, we need to find a digit (let's call it 'x') such that (0x) × x is less than or equal to 29. - Trying 5: (05) × 5 = 25 - Trying 6: (06) × 6 = 36 (too high) So, we take 5. Now, we have: - Current result: 0.5 - Subtract 25 from 29: 29 - 25 = 4 ### Step 6: Bring down the next pair Now, bring down the next pair (16) next to the remainder (4). We now have 416. ### Step 7: Double the current result Double the current result (which is 0.5). So, 0.5 × 2 = 1. ### Step 8: Find the next digit Now, we need to find a digit (let's call it 'y') such that (1y) × y is less than or equal to 416. - Trying 3: (13) × 3 = 39 - Trying 4: (14) × 4 = 56 - Trying 5: (15) × 5 = 75 - Trying 6: (16) × 6 = 96 - Trying 7: (17) × 7 = 119 - Trying 8: (18) × 8 = 144 - Trying 9: (19) × 9 = 171 - Trying 10: (20) × 10 = 200 - Trying 11: (21) × 11 = 231 - Trying 12: (22) × 12 = 264 - Trying 13: (23) × 13 = 299 - Trying 14: (24) × 14 = 336 - Trying 15: (25) × 15 = 375 - Trying 16: (26) × 16 = 416 So, we take 6. Now, we have: - Current result: 0.54 - Subtract 416 from 416: 416 - 416 = 0 ### Final Result Since we have no remainder left, the square root of 0.2916 is **0.54**. ---
