Question

ASAP Please answer. Three students sit in the first row. In the second row, 3 students sit behind each of those students, and so on. Write an expression with exponents to show how many students sit in the third row? How many total students are seated?

Answer 1

3^2, 9 students.

Explanation:

I'm not 100 percent sure about this but I'm pretty sure that because there are 3 rows you can just do 3^2 which is 9.

Answer 2

3^x. 39

Explanation:

To find the expression, we know the first row is 3 and the next row is 9. So the pattern is multiply by 3. That means the expression is 3^x. Following that, we know the third row is 27. 3 + 9 + 27 = 39
