. Find the square root of 1369 by long division method
Best Answer
Explanation:
First write the number 1369 and make pairs from the right.
So,69 and 13 are two pairs.
Now we will find that number whose square is less than or equal to 13.
2×2 =4
3×3 =9
4×4 =16
Since 16>13, we use 3×3 =9
So writing on top and left side & 9 below 13
Now we find remainder,
13 - 9= 4
Take pair 69 down.
Lastly, we find the number which is less than or equal to 469
67×5 =335
67×6 =402
67×7 =469
Since,67×7 =469 We use that.
Final answer:
Thus, Square root of 1369 =37.
