Answer 3

To solve this problem, it seems like you have a series of multiplication expressions in the form of "number:number" separated by semicolons. Each expression represents multiplying the two numbers together. Let's solve it step by step:

1. 675270 * 30 = 20,258,100
2. 900205600 * 700 = 630,144,920,000
3. 768240 * 40 = 30,729,600
4. 400238400 * 600 = 240,142,240,000

Now, let's list the results in a column:

Copy code
  20,258,100
630,144,920,000
  30,729,600
240,142,240,000

To perform the addition, just add the numbers in the column:

diffCopy code
     20,258,100
+ 630,144,920,000
+     30,729,600
+ 240,142,240,000
_________________
= 871,075,228,700

So, the result of the expressions is 871,075,228,700.
