simplify 3ln(x)+4ln(y)-5ln(z)

simplify

3 ln (x) + 4 ln (y) - 5 ln (z)

ln (\frac{x ^{3} y ^{4}}{z ^{5}})

Solution steps

3 ln (x) + 4 ln (y) - 5 ln (z)

Apply log rule:

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

3 ln (x) = ln (x^{3})

= ln (x^{3}) + 4 ln (y) - 5 ln (z)

Apply log rule:

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

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

= ln (x^{3}) + ln (y^{4}) - 5 ln (z)

Apply log rule:

lo g_{c} (a) + lo g_{c} (b) = lo g_{c} (ab)

ln (x^{3}) + ln (y^{4}) = ln (x^{3} y^{4})

= ln (x^{3} y^{4}) - 5 ln (z)

Apply log rule:

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

5 ln (z) = ln (z^{5})

= ln (x^{3} y^{4}) - ln (z^{5})

Apply log rule:

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

ln (x^{3} y^{4}) - ln (z^{5}) = ln (\frac{x ^{3} y ^{4}}{z ^{5}})

= ln (\frac{x ^{3} y ^{4}}{z ^{5}})

lo g_{2} (3) - lo g_{2} (5)

lo g_{4} (\frac{( 3 x - 7 )}{( 2 x + 1 ) 5 x + 7})

2 lo g_{b} (3) + lo g_{b} (6)

lo g_{10} (\frac{x ^{5}}{2})

lo g_{x} (2 x)
