otez555 [7]

Answer:

D=3.88

Step-by-step explanation:

We can use this equation:

N=R^{D}

Where:

  • N is the increase factor (N=512)
  • R is the reduce factor (R=8)
  • D is the dimension

512=5^{D}

We just need to solve it for D

D=log(512)/log(5)

D=3.88

Therefore the dimension will be 3

I hope it helps you!
