\cfrac{6!}{3!}\implies \cfrac{6\cdot 5\cdot 4\cdot \qquad 3\cdot 2\cdot 1}{3\cdot 2\cdot 1}\implies \cfrac{6\cdot 5\cdot 4\cdot 3!}{3!}\implies 6\cdot 5\cdot 4\implies 120

Answer:


  • \boxed{\sf{120}}

Explanation:

Use the factorials formula.

Factorials formula:


\Longrightarrow: \sf{(n!)/((n-m)!)=n*(n-1)* (n-m+1),\:\quad \:n > \:m}

→ 6!/3!=6*5*4

⇒ 6*5*4

Solve a order of operations.

PEMDAS stands for:

  • Parenthesis
  • Exponents
  • Multiply
  • Divide
  • Add
  • Subtract

First, multiply.

→ 6*5*4

⇒ 6*5=30

⇒ 30*4=120

= 120

  • Therefore, the correct answer is 120.

I hope this helps you! Let me know if my answer is wrong or not.
