Answer 2

A) To solve the expression 6390 * 78400 + 23808 ÷ 768, we can follow the order of operations (PEMDAS/BODMAS). First, we perform the division, and then we perform the multiplication and addition.

The division 23808 ÷ 768 equals 31. Next, we multiply 6390 by 78400, which equals 501,096,000. Finally, we add the result of the multiplication to the result of the division: 501,096,000 + 31 = 501,096,031.

Therefore, the solution to the expression 6390 * 78400 + 23808 ÷ 768 is 501,096,031.

B) To solve the expression 17284679 + 75852 ÷ 84 * 3007, we again follow the order of operations. First, we perform the division, then the multiplication, and finally the addition.

The division 75852 ÷ 84 equals 903. Next, we multiply 903 by 3007, which equals 2,716,721. Finally, we add the result of the multiplication to 17284679: 2,716,721 + 17,284,679 = 19,001,400.

Therefore, the solution to the expression 17284679 + 75852 ÷ 84 * 3007 is 19,001,400.
