Simplify:
$$49\times (123÷3)+13\times 25$$

According to the BODMAS rule, we solve the brackets first, followed by division, multiplication, and addition.
Given expression:

$$49\times (123÷3)+13\times 25$$

Step 1: Solve the division inside the bracket:

$$123÷3=41$$

The expression becomes:

$$49\times 41+13\times 25$$

Step 2: Perform the multiplications:

$$49\times 41=2009$$

$$13\times 25=325$$

Step 3: Perform the addition:

$$2009+325=2334$$

Thus, the simplified value is $2334$.
