AI Generated Solution

The correct Answer is:
To solve the expression \((6!)/(3!)\), we will follow these steps: ### Step 1: Understand Factorials Factorials are defined as the product of all positive integers up to a certain number. For example: - \(n! = n \times (n-1) \times (n-2) \times \ldots \times 1\) ### Step 2: Write Out the Factorials We will write out \(6!\) and \(3!\): - \(6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1\) - \(3! = 3 \times 2 \times 1\) ### Step 3: Substitute the Factorials into the Expression Now we can substitute these into our expression: \[ \frac{6!}{3!} = \frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{3 \times 2 \times 1} \] ### Step 4: Cancel Out the Common Terms Notice that \(3!\) (which is \(3 \times 2 \times 1\)) appears in both the numerator and the denominator. We can cancel these terms: \[ \frac{6 \times 5 \times 4 \times \cancel{3 \times 2 \times 1}}{\cancel{3 \times 2 \times 1}} = 6 \times 5 \times 4 \] ### Step 5: Calculate the Remaining Product Now, we will calculate \(6 \times 5 \times 4\): - First, calculate \(6 \times 5 = 30\) - Then, multiply \(30 \times 4 = 120\) ### Final Answer Thus, the value of \(\frac{6!}{3!}\) is \(120\). ---
