limit as x approaches 0 of ((4^x-1))/x

x \to 0 lim (\frac{( 4 ^{x} - 1 )}{x})

2 ln (2)

Decimal

1.38629 \dots

Solution steps

x \to 0 lim (\frac{4 ^{x} - 1}{x})

Apply L'Hopital's Rule

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

Plug in the value

x = 0

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

Simplify

= 2 ln (2)
