"Four 4's"

Your equation's on the top are wrong. Sorry but sqrt(sqrt 4) isn't 1.

[x] stands for the "floor" or "whole part" function - the largest integer less than or equal to x.

1 < sqrt(sqrt(4)) = sqrt(2) < 2

Therefore, [sqrt(sqrt(4))] = 1.

Do not be sorry. Thinking and noticing this how one does the learning.

All the best,
Alexander Bogomolny
