Abstract: Modeling the potential by an inverse square law in terms of the tachyon field $[V(T)=\ensuremath{\beta}{T}^{\ensuremath{-}2}]$ we find an exact solution for a spatially flat isotropic universe. We show that for $\ensuremath{\beta}>2\sqrt{3}/3$ the model undergoes power-law inflation. A way to construct other exact solutions is specified and exemplified.
