# Distinct Roots (not that kind)

Number Theory Level pending

Define $$M_i$$ as the minimum positive integer such that all elements in the set $$S = \left\{M_i, \left\lfloor\sqrt[2]{M_i}\right\rfloor, ..., \left\lfloor\sqrt[i]{M_i}\right\rfloor\right\}$$ are pairwise distinct. What are the last three digits of $$\sum _{i=2}^{10} M_i$$?
