It should be 3^9
3*3*3*3*3*3*3*3*3 = 19683
so the prime factorization should be that

Answer:

21 = 3 x 7

Step-by-step 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

<h3>Answer:   choice F) 12 & 1/2 square yards.</h3>

=====================================================

We'll use this formula

a & b/c = (a*c + b)/c

to convert from a mixed number to an improper fraction.

Let's convert the first mixed number to an improper fraction

a & b/c = (a*c + b)/c

3 & 3/4 = (3*4 + 3)/4

3 & 3/4 = 15/4

Repeat the same idea for the second mixed number as well

a & b/c = (a*c + b)/c

3 & 1/3 = (3*3 + 1)/3

3 & 1/3 = 10/3

--------------------

In short we have

  • 3 & 3/4 = 15/4
  • 3 & 1/3 = 10/3

Doing these conversions is useful to be able to multiply the values like so:

(15/4)*(10/3) = (15*10)/(4*3) = 150/12 = (6*25)/(6*2) = 25/2

Now use your calculator to find that 25/2 = 12.5

We can then say....

12.5 = 12 + 0.5 = 12 + (1/2) = 12 & 1/2

The answer is choice F) 12 & 1/2 square yards.
