What is the value of \(\frac{10!}{8!}\)?

  • A.2
  • B.20
  • C.90
  • D.180

Answer: C

We can expand the factorials. \(10! = 10 \times 9 \times 8 \times 7 \times ... \times 1\) and \(8! = 8 \times 7 \times ... \times 1\). So, \(\frac{10!}{8!} = \frac{10 \times 9 \times 8!}{8!} = 10 \times 9 = 90\).
