What is the value of 8!/7!?

Answer and explanation

Correct answer: 8

Factorial notation represents a product of consecutive positive integers. Expand only the part needed for cancellation: 8! = 8 × 7!. Therefore, 8!/7! = (8 × 7!)/7! = 8, since 7! is nonzero and cancels from numerator and denominator. Option D is consequently correct. A common error is to multiply 8 by 7 and choose 56, as in option C; that would ignore the division by 7!. Option A gives the remaining factorial factor rather than the quotient, while option B results from adding 8 and 7 instead of simplifying the fraction. The efficient method is to use n! = n × (n − 1)! rather than calculate either factorial completely.
