Find the product using suitable rearrangement:
`5xx30xx40`

Answer

To find the product of \(5 \times 30 \times 40\) using suitable rearrangement, we can follow these steps:

### Step 1: Rearrange the multiplication
We can rearrange the multiplication to make it easier. Let's group \(5\) and \(40\) together first:
\[ (5 \times 40) \times 30 \]

### Step 2: Calculate \(5 \times 40\)
Now, we calculate \(5 \times 40\):
\[ 5 \times 40 = 200 \]

### Step 3: Multiply the result by \(30\)
Next, we take the result from the previous step and multiply it by \(30\):
\[ 200 \times 30 \]

### Step 4: Simplify \(200 \times 30\)
To calculate \(200 \times 30\), we can break it down:
\[ 200 \times 30 = 200 \times (3 \times 10) = (200 \times 3) \times 10 \]
Calculating \(200 \times 3\):
\[ 200 \times 3 = 600 \]
Now, multiply by \(10\):
\[ 600 \times 10 = 6000 \]

### Final Answer
Thus, the product \(5 \times 30 \times 40\) is:
\[ \boxed{6000} \]
