Question

Does anyone know how to find square root quickly?

Answer 1

Step-by-step explanation: Make a perfect square list

This is one that goes to 15

`√(1) √(4) √(9) √(16) √(25) √(36) √(49) √(64) √(81) √(100) √(121) √(144) √(169) √(196) √(225)`

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

The numbers on top are the square root and the numbers under are the answer or squared numbers. There is also a way to solve them if the number is between a number in the list like 18 but i don't feel like explaining that this is just the basic squares.

Answer 2

Answer: The quick way is to square the half of it.

Step-by-step explanation: You divide your main number by 2 and figure out that half. If it is still too big, divide by 2 again. If you need to keep repeating that is fine. Thank you multiply your answer by however many times you divided by 2.
