How does the base of the logarithm change when calculating the height of a tree depending on the type of tree?

The base of the logarithm when calculating the height of a tree depends on the number of children (branches) of each node, that is, on the degree of the tree.

• For a binary tree (each node has up to 2 children), the height is approximately (O(\log_2 n)), where (n) is the number of nodes.
• For B-trees with order (m) (each node has up to (m) children), the height is approximately (O(\log_m n)).

Thus, the base of the logarithm is equal to the maximum number of children in a node. The greater the branching, the lower the height of the tree for the same number of elements.

This is important for estimating the efficiency of search, insertion, and deletion operations, which depend on the height of the tree.
