simplify 4ln(x)-1/2 ln(y)

simplify

4 ln (x) - \frac{1}{2} ln (y)

ln (\frac{x ^{4} y}{y})

Solution steps

4 ln (x) - \frac{1}{2} ln (y)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

4 ln (x) = ln (x^{4})

= ln (x^{4}) - \frac{1}{2} ln (y)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

\frac{1}{2} ln (y) = ln (y^{\frac{1}{2}})

= ln (x^{4}) - ln (y^{\frac{1}{2}})

Apply log rule:

lo g_{c} (a) - lo g_{c} (b) = lo g_{c} (\frac{a}{b})

ln (x^{4}) - ln (y^{\frac{1}{2}}) = ln (\frac{x ^{4}}{y ^{\frac{1}{2}}})

= ln (\frac{x ^{4}}{y ^{\frac{1}{2}}})

Simplify

\frac{x ^{4}}{y ^{\frac{1}{2}}} : \frac{x ^{4} y}{y}

= ln (\frac{x ^{4} y}{y})

25 ln (e \frac{2}{5})

\frac{1}{3} ln (64) - ln (12)

lo g_{7} (\frac{7 x ^{9}}{y})

ln (9.65 \cdot 1 0^{- 6})

lo g_{10} ((\frac{u ^{2}}{v})^{3})
