How can you find approximations (estimations) of square roots?
Luda [366]
To find approximations of square roots, you should find the nearest prefect square. For example if your looking to approximate the square rot of 10, the closest perfect square is 9 and the square root of that is three. Thus, you can say that the square root is about 3.
