Use distributive property of multiplication over addition/ subtraction and evaluate:
`2389xx156-2389xx56`

Options

A. `2,38,900`
B. `2,38,920`
C. `2,39,900`
D. `2,35,900`

Answer

To solve the expression \( 2389 \times 156 - 2389 \times 56 \) using the distributive property of multiplication over subtraction, we can follow these steps:

### Step 1: Identify the common factor
In the expression \( 2389 \times 156 - 2389 \times 56 \), we can see that \( 2389 \) is a common factor in both terms.

### Step 2: Factor out the common term
Using the distributive property, we can factor out \( 2389 \):
\[ 2389 \times (156 - 56) \]

### Step 3: Simplify the expression inside the parentheses
Now, we need to subtract \( 56 \) from \( 156 \):
\[ 156 - 56 = 100 \]

### Step 4: Substitute back into the expression
Now we substitute back into our expression:
\[ 2389 \times 100 \]

### Step 5: Perform the multiplication
Now, we multiply \( 2389 \) by \( 100 \):
\[ 2389 \times 100 = 238900 \]

### Final Answer
Thus, the final answer is:
\[ \boxed{238900} \]
