simplify log_{10}(x(x^2+7)^{-1/2})

simplify

lo g_{10} (x (x^{2} + 7)^{- \frac{1}{2}})

lo g_{10} (x) - \frac{1}{2} lo g_{10} (x^{2} + 7)

Solution steps

lo g_{10} (x (x^{2} + 7)^{- \frac{1}{2}})

Simplify

x (x^{2} + 7)^{- \frac{1}{2}} : \frac{x}{( x ^{2} + 7 ) ^{\frac{1}{2}}}

= lo g_{10} (\frac{x}{( x ^{2} + 7 ) ^{\frac{1}{2}}})

Apply log rule:

lo g_{a} (\frac{x}{y}) = lo g_{a} (x) - lo g_{a} (y)

lo g_{10} (\frac{x}{( x ^{2} + 7 ) ^{\frac{1}{2}}}) = lo g_{10} (x) - lo g_{10} ((x^{2} + 7)^{\frac{1}{2}})

= lo g_{10} (x) - lo g_{10} ((x^{2} + 7)^{\frac{1}{2}})

Simplify

lo g_{10} ((x^{2} + 7)^{\frac{1}{2}}) : \frac{1}{2} lo g_{10} (x^{2} + 7)

= lo g_{10} (x) - \frac{1}{2} lo g_{10} (x^{2} + 7)

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

lo g_{2} (\frac{8}{x})

ln (\frac{x ^{2}}{y})

lo g_{10} (x - 3) + lo g_{10} (x + 3)

lo g_{10} (\frac{x ^{4}}{y ^{2}})
