limit as x approaches infinity of ln(9x)-ln(x+7)

x \to \infty lim (ln (9 x) - ln (x + 7))

2 ln (3)

Decimal Notation

2.19722 \dots

Solution steps

x \to \infty lim (ln (9 x) - ln (x + 7))

Apply log rule:

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

ln (9 x) - ln (x + 7) = ln (\frac{9 x}{x + 7})

= x \to \infty lim (ln (\frac{9 x}{x + 7}))

Apply the Limit Chain Rule:

2 ln (3)

= 2 ln (3)

\int \frac{1}{ln ( x ) x} d x

\int \frac{ln ( x )}{2 x} d x

f (x) = (1 n (x^{3}))

x \to 19 lim (\frac{x - 19}{x ^{2} - 361})

\int e^{x} 31 + e^{x} d x

What is the limit as x approaches infinity of ln(9x)-ln(x+7) ?
The limit as x approaches infinity of ln(9x)-ln(x+7) is 2ln(3)
