\(\dfrac{10!}{3!} = \dfrac{10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot 2\cdot1}{3\cdot2\cdot1} = \dfrac{10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot\cancel{3\cdot2\cdot1}}{\cancel{3\cdot2\cdot1}}\)
\[~~~~~~~=10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\]

The answer is
10 x 9 x 8 x 7 x 6 x 5 x 4
First we multiply from left to right, so what is 10 x 9?
