Sarah is making strings of beads in the first string she uses 3 beads and she triples the number of beads in each of the next strings identify the number of beads she uses in 5 string

She uses 729 beads for 5 strings.

Step-by-step explanation:

1 string :  3 × 3 = 9 beads

2 string : 9 × 3 = 27 beads

3 string : 27× 3 = 81  beads

4 string : 81 × 3 = 243 beads

5 string :  243 × 3 = 729 beads

729

Step-by-step explanation:

1) 3×3=9

2) 9×3=27

3) 27×3=81

4) 81×3=243

5) 243×3=729

a negative exponent is translated as follows:

so, we have
