simplify ln(7)+2ln(3)

Solution

simplify

ln (7) + 2 ln (3)

Solution

ln (63)

+1

Solution steps

ln (7) + 2 ln (3)

Apply log rule:

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

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

= ln (7) + ln (3^{2})

Apply log rule:

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

ln (7) + ln (3^{2}) = ln (3^{2} \cdot 7)

= ln (3^{2} \cdot 7)

7 \cdot 3^{2} = 63

= ln (63)
