simplify 2ln(3)+2ln(4)

Solution

simplify

2 ln (3) + 2 ln (4)

Solution

2 ln (12)

+1

Solution steps

2 ln (3) + 2 ln (4)

Apply log rule:

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

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

= ln (3^{2}) + 2 ln (4)

Apply log rule:

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

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

= ln (3^{2}) + ln (4^{2})

Apply log rule:

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

ln (3^{2}) + ln (4^{2}) = ln (3^{2} \cdot 4^{2})

= ln (3^{2} \cdot 4^{2})

3^{2} \cdot 4^{2} = 144

= ln (144)

Rewrite

144

in power-base form:

144 = 1 2^{2}

= ln (1 2^{2})

Apply log rule:

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

ln (1 2^{2}) = 2 ln (12)

= 2 ln (12)
