You complete 3 centimeters of a necklace in an hour. each hour after the first, you triple the length iof the necklace. write an expression using the exponents for the length of the necklace after 3 hours. then find the length

Length after 3 hours = 27 centimeters

Step-by-step explanation:

Let us solve this while making a table

Hours(n)             Length (L)

 1                       3

 2                      3 x 3 = 9 =

 3                      9 x 3 = 27 =

4                       27 x 3 = 81 =

 n                    

Hence we can draw an expresssion as

to measure the length of the necklace after n hours.

Hence

First hour: 3 = 3¹

Second hour: (3) x 3 = 3²

Third hour: (3 x 3) x 3 = 3³

Fourth hour: (3 x 3 x 3) x 3 = 3⁴

Do you see the pattern? where n is the number of hours

3³,
