Question

On a tree, the trunk splits into 5 branches. Then each branch splits into 5 smaller branches, and each of those branches splits into 5 very thin branches. How many very thin branches are on the tree?

Answer 1

There are 125 very thin branches.

• 5 branches x 5 smaller branches = 25 smaller branches
• 25 smaller branches x 5 very thin branches = 125 very thin branches
• 125 very thin branches in your final answer!
