Let's solve \( 73 \times 45 \) step-by-step, showing the work.

### Step-by-step multiplication:

1. **Break the multiplication into parts using the distributive property:**
   \[
   73 \times 45 = 73 \times (40 + 5) = (73 \times 40) + (73 \times 5)
   \]

2. **Multiply each part:**

   - First, multiply \( 73 \times 40 \):
     \[
     73 \times 40 = 2920
     \]

   - Now, multiply \( 73 \times 5 \):
     \[
     73 \times 5 = 365
     \]

3. **Add the two products together:**
   \[
   2920 + 365 = 3285
   \]

### Final Answer:
\[
73 \times 45 = 3285
\]
