Math Question: If Alex wants to distribute 6400 cookies equally among 80 friends, how many cookies will each friend receive?

To find the number of cookies each friend will receive, we divide the total number of cookies (6400) by the number of friends (80). Thus, each friend will receive 80 cookies. This can be calculated by dividing 6400 by 80. Therefore, each friend will receive an equal share of 80 cookies.

Math question: What is the result if you divide 6400 by 4, multiply it by 5, subtract 100, and then add 2000?

To calculate, divide 6400 by 4 to get 1600. Next, multiply 1600 by 5 which equals 8000. Subtract 100 from 8000 to get 7900. Finally, add 2000 to 7900 to obtain the result of 9900. The answer is 9900.

What is the square root of 6400?
