  It has been proposed that, without invoking supersymmetry, it is possible to
solve the hierarchy problem provided the fundamental scale in the higher
dimensional theory is at a much lower scale than the Planck scale. In this
paper we consider a toy model where we allow $4+d$ dimensions to evolve from a
region determined by the new fundamental scale, which is in our case is
electro-weak scale. We further investigate whether it is possible to inflate
not only the 3 uncompactified dimensions but also the extra dimensions. We
require around 70 e-foldings to stabilize the size of two extra dimensions from
$M_{\rm EW}^{-1}$ to the required 1 mm size. This can be easily achieved during
inflation, but once inflation ends their evolution is governed by the dynamical
history of the universe in a similar way that of Brans-Dicke field in
generalized Einstein theories. We also show that we achieve the right level of
density contrast without invoking any specific potential. The density contrast
depends on the number of extra dimensions and upon the amplitude of the
potential.
