simplify ln((e^7)/9)

Solution

simplify

ln (\frac{e ^{7}}{9})

Solution

7 - 2 ln (3)

+1

Decimal Notation

4.80277 \dots

Solution steps

ln (\frac{e ^{7}}{9})

Apply log rule:

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

ln (\frac{e ^{7}}{9}) = ln (e^{7}) - ln (9)

= ln (e^{7}) - ln (9)

Apply log rule:

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

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

= 7 ln (e) - ln (9)

7 ln (e) = 7

= 7 - ln (9)

ln (9) = 2 ln (3)

= 7 - 2 ln (3)
