√385
385 is not a perfect square number, but it is too close to 400 so that its square root would be close to 20, that is ≥ 19.5...
To find it more precisely, you need to work a little bit.
√385 = 19. ...
1. 19; double 1 so 19 becomes 29.
2. 29*9 = 261, subtract it from 285 (385 - 100).
285 - 261 = 24, add 2 zeros to 24; 2400 (we add pairs of zeros after the decimal point)
2. 29; double 9, so 29 becomes 38
Now think for a number that will multiply 38_ so that the product to be close to 2400
386*6 = 2316 and 2400 - 2316 = 84, add 2 zeros to 84; 8400
√385 = 19.6 ...
3. 386; double 6, so 386 becomes 392
Now think for a number that will multiply 392_ so that the product to be close to 8400
3922*2 = 7844 and 8400 - 7844 = 556, add 2 zeros to 556; 55600
√385 = 19.62 ...

Simplify the square root of 512?
The idea is to take out perfect squares. The largest perfect square in this case is 256, which is the square of 16 (if you have trouble figuring this out, you can take out a smaller perfect square first, and then see if you find additional perfect squares). In any case, the end result should not have a factor that is a perfect square. Using the symbol "root()" for square root: root(512) = root(256 x 2) = root(256) x root(2) = 16 root(2)
