log b â¡ ( x y ) = log b â¡ ( x y â 1 ) = log b â¡ ( x ) + log b â¡ ( y â 1 ) = log b â¡ ( x ) â log b â¡ ( y ) {\displaystyle \log _{b}{\bigg (}{\frac {x}{y}}{\bigg )}=\log _{b}(xy^{-1})=\log _{b}(x)+\log _{b}(y^{-1})=\log _{b}(x)-\log _{b}(y)}.
If you wanted an 800 grit polish, which is still very reflective, there arenât as many steps, so the price is decreased. Polished concrete, in general, can range anywhere from $2.00 per square foot to $7.00 per square foot. Glossy Floors, before giving an estimate, takes the time to examine the floor very carefully.
Basic cost for a polished concrete floor that requires only a few levels of grinding, according to Greg Demmert of Demmert & Assoc. in Los Angeles. $3-$8/ sq ft. For concrete floors requiring more in-depth grinding or including coloring with stains and dyes, according to Demmert. In the Denver area.osts for polished concrete will range depending upon the area of the country and the contractor. Many offer different price points for various levels and designs for polished concrete.
