simplify 2ln(7)-2ln(2)

Solution

simplify

2 ln (7) - 2 ln (2)

Solution

ln (\frac{49}{4})

+1

Solution steps

2 ln (7) - 2 ln (2)

Apply log rule:

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

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

= ln (7^{2}) - 2 ln (2)

Apply log rule:

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

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

= ln (7^{2}) - ln (2^{2})

Apply log rule:

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

ln (7^{2}) - ln (2^{2}) = ln (\frac{7 ^{2}}{2 ^{2}})

= ln (\frac{7 ^{2}}{2 ^{2}})

\frac{7 ^{2}}{2 ^{2}} = \frac{49}{4}

= ln (\frac{49}{4})
