simplify log_{10}(x)+log_{10}(x+9)

simplify

lo g_{10} (x) + lo g_{10} (x + 9)

lo g_{10} (x (x + 9))

Solution steps

lo g_{10} (x) + lo g_{10} (x + 9)

Apply log rule:

lo g_{a} (x) + lo g_{a} (y) = lo g_{a} (x y)

lo g_{10} (x) + lo g_{10} (x + 9) = lo g_{10} (x (x + 9))

= lo g_{10} (x (x + 9))

\frac{4}{5} ln (2)

lo g_{6} (x) - lo g_{6} (x^{3})

lo g_{b} (9) + lo g_{b} (8)

ln (5) + 3 ln (x) + 4 ln (x^{2} + 4)

ln (\frac{0.75}{0.25})
