10. For (a) through (d) the dimension is log(3)/log(2).

(f) The number of small copies is just the number of IFS functions, the size of each copy is determined by the scaling factor. When the IFS generates a fractal to which

d = log(N)/log(1/s)

is applicable, E and F have no influence on the dimension. Usually, for this equation to be applicable, all the IFS functions must have the same R and S values, and R = S.

If R = S for each piece, but the R values differ for different pieces, the generalization of this equation is the Moran equation: d is the solution of

R_{1}^{d} + R_{2}^{d} + ... +
R_{N}^{d} = 1.

If some R_{i} is different from S_{i}, the fractal is
*self-affine*, and the dimension computation is much more difficult.
