Question

Sam sent an email to 3 friends on Monday . Each of the friends then sent an email to 3 friends on Tuesday . On Wednesday each of those friends then sent an email to 3 friends . Write the prime factorization of the number of email that were sent on Wednesday

Answer 1

it should be 3^9
3*3*3*3*3*3*3*3*3 = 19683
so the prime factorization should be that
oh yeah * = the times sign

Answer 2

21 = 3 x 7

Explanation:

If Sam sent three friends an email on Monday and each friend sent an email to 3 friends on Tuesday and total of 3+3*3= 12 emails were sent by Tuesday. on Wednesday each of the friends that received those emails sent it to 3 friends so the total amount of emails sent by Wednesday is:

`=3+3*3+3*3=21`

21 emails were sent by Wednesday. The prime factorization of 21 is 3 x 7
