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.
Marble varieties of floor tile are readily available at an average of $6 per square foot, and polished marble wall tile can be found at $10.90 per square foot. Granite shower tile is available at an average of $3.49 per square foot to $6.99 per square foot.
