If a number’s composite form is 343, which of the following shows its exponential form as a product of prime numbers? a.7 · 49 b.73 c.49 d.343

a is the answer

Step-by-step explanation:

7×7×7=343

7×7=49

49×7=343

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
