Evaluate: `20 times 39 times 5`

Answer

To evaluate the expression \( 20 \times 39 \times 5 \), we can break it down into steps:

### Step 1: Multiply 20 and 39
First, we will multiply \( 20 \) by \( 39 \).

\[ 20 \times 39 \]

To do this, we can use the distributive property:

\[ 20 \times 39 = 20 \times (30 + 9) = (20 \times 30) + (20 \times 9) \]

Calculating each part:

- \( 20 \times 30 = 600 \)
- \( 20 \times 9 = 180 \)

Now, we add these two results together:

\[ 600 + 180 = 780 \]

So,

\[ 20 \times 39 = 780 \]

### Step 2: Multiply the result by 5
Now, we will multiply the result \( 780 \) by \( 5 \):

\[ 780 \times 5 \]

We can calculate this directly:

\[ 780 \times 5 = 3900 \]

### Final Answer
Thus, the final result of \( 20 \times 39 \times 5 \) is:

\[ \boxed{3900} \]
