16. You sent an email to 8 friends. They each forwarded
the email to 8 friends. And those friends each forwarded
the email to 8 friends. The chain of emails is represented
by the expression 8 +82 + 8³. How many people were
sent your email?

Answer 1

To find the number of people who received your email, calculate the expression 8 + 8^2 + 8^3. The total number of people who received your email is 584.

Step-by-step explanation:

To find the number of people who received your email, you need to calculate the expression 8 + 82 + 83. This expression represents the number of people who received the email directly (8), plus the number of people who received the email through the first set of friends (82), plus the number of people who received the email through the second set of friends (83). Calculate each part separately:

1. 8 + 82 = 8 + 64 = 72
2. 83 = 512

Now, add the results together: 72 + 512 = 584

Therefore, a total of 584 people were sent your email.
