Final answer:
The number of spanning trees of an n-cycle graph for any n≥3 is n, as each edge removal creates a unique spanning tree.
Step-by-step explanation:
To count the total number of spanning trees of an n-cycle graph for any n≥3, you can use the formula derived from the matrix-tree theorem. For an n-cycle graph, which is a graph that forms a single loop of n nodes, there are n spanning trees. This is because you can remove any one edge to create a spanning tree, and since there are n edges, there are n different ways to do this, resulting in n different spanning trees.
