What is the simplified value of \( \frac{7!+6!}{6!} \)?

Answer and explanation

Correct answer: 8

Since \(7!=7\times6!\), \(\frac{7!+6!}{6!}=\frac{7\times6!+6!}{6!}=\frac{8\times6!}{6!}=8\). Option 7 is only the value of \(7!/6!\); it ignores the additional \(6!\) term. Exam tip: in a sum of factorial terms, first factor out the smaller common factorial.
