limit as x approaches infinity of (2^x)/(3^{x-1)}

x \to \infty lim (\frac{2 ^{x}}{3 ^{x - 1}})

0

Solution steps

x \to \infty lim (\frac{2 ^{x}}{3 ^{x - 1}})

Simplify

3^{x - 1} : 3^{x} \cdot 3^{- 1}

= x \to \infty lim (\frac{2 ^{x}}{3 ^{x} \cdot 3 ^{- 1}})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= \frac{1}{3 ^{- 1}} \cdot x \to \infty lim (\frac{2 ^{x}}{3 ^{x}})

\frac{1}{3 ^{- 1}} = 3

= 3 \cdot x \to \infty lim (\frac{2 ^{x}}{3 ^{x}})

Apply exponent rule:

\frac{a ^{c}}{b ^{c}} = (\frac{a}{b})^{c}

= 3 \cdot x \to \infty lim ((\frac{2}{3})^{x})

Apply the common limit:

x \to \infty lim (a^{x}) = 0, 0 < a < 1

= 3 \cdot 0

Simplify

= 0

\int 2 - x d x

\frac{d}{d x} (cos (\frac{π}{2} x))

\int_{- π}^{0} x d x

\int 2 e^{x^{2}} d x

2 x^{2} y^{^{'}} = y^{^{'}} + 4 x e^{- y}
