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!
