limit as x approaches 0 of (9^x-1)/x

x \to 0 lim (\frac{9 ^{x} - 1}{x})

2 ln (3)

Decimal

2.19722 \dots

Solution steps

x \to 0 lim (\frac{9 ^{x} - 1}{x})

Apply L'Hopital's Rule

= x \to 0 lim (\frac{2 ln ( 3 ) \cdot 9 ^{x}}{1})

Plug in the value

x = 0

= \frac{2 ln ( 3 ) \cdot 9 ^{0}}{1}

Simplify

= 2 ln (3)
