In a binary tree, the maximum number of nodes at level _________ is 2^(h) where 'h' is the height of the tree.

In a binary tree, the number of nodes at a particular level follows the formula 2^(h), where 'h' is the height of the tree. The root node is considered to be at level 0, so the maximum number of nodes at level 3 would be 2^(3) = 8 nodes. This concept is important in understanding the structure and size of binary trees based on their height.
