simplify 2ln(5)-3ln(2)

Solution

simplify

2 ln (5) - 3 ln (2)

Solution

ln (\frac{25}{8})

+1

Decimal Notation

1.13943 \dots

Solution steps

2 ln (5) - 3 ln (2)

Apply log rule:

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

2 ln (5) = ln (5^{2})

= ln (5^{2}) - 3 ln (2)

Apply log rule:

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

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

= ln (5^{2}) - ln (2^{3})

Apply log rule:

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

ln (5^{2}) - ln (2^{3}) = ln (\frac{5 ^{2}}{2 ^{3}})

= ln (\frac{5 ^{2}}{2 ^{3}})

\frac{5 ^{2}}{2 ^{3}} = \frac{25}{8}

= ln (\frac{25}{8})
