simplify 2ln(6)-ln(4)

Solution

simplify

2 ln (6) - ln (4)

Solution

2 ln (3)

+1

Solution steps

2 ln (6) - ln (4)

Apply log rule:

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

2 ln (6) = ln (6^{2})

= ln (6^{2}) - ln (4)

Apply log rule:

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

ln (6^{2}) - ln (4) = ln (\frac{6 ^{2}}{4})

= ln (\frac{6 ^{2}}{4})

\frac{6 ^{2}}{4} = 9

= ln (9)

Rewrite

9

in power-base form:

9 = 3^{2}

= ln (3^{2})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (3^{2}) = 2 ln (3)

= 2 ln (3)
