simplify ln(4/1)

Solution

simplify

ln (\frac{4}{1})

Solution

2 ln (2)

+1

Solution steps

ln (\frac{4}{1})

Apply log rule:

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

ln (\frac{4}{1}) = ln (4) - ln (1)

= ln (4) - ln (1)

Apply log rule:

lo g_{a} (1) = 0

= ln (4) - 0

ln (4) - 0 = ln (4)

= ln (4)

Rewrite

4

in power-base form:

4 = 2^{2}

= ln (2^{2})

Apply log rule:

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

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

= 2 ln (2)
