integral of 8^{3x-1}

\int 8^{3 x - 1} d x

\frac{2 ^{9 x - 3}}{9 ln ( 2 )} + C

Solution steps

\int 8^{3 x - 1} d x

8^{3 x - 1} = 8^{- 1} \cdot 8^{3 x}

= \int 8^{- 1} \cdot 8^{3 x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 8^{- 1} \cdot \int 8^{3 x} d x

Apply exponent rule:

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

= \frac{1}{8} \cdot \int 8^{3 x} d x

Simplify

8^{3 x} : 51 2^{x}

= \frac{1}{8} \cdot \int 51 2^{x} d x

\int a^{x} d x = \frac{a ^{x}}{ln a}

= \frac{1}{8} \cdot \frac{51 2 ^{x}}{ln ( 512 )}

Simplify

\frac{1}{8} \cdot \frac{51 2 ^{x}}{ln ( 512 )} : \frac{2 ^{9 x - 3}}{9 ln ( 2 )}

= \frac{2 ^{9 x - 3}}{9 ln ( 2 )}

Add a constant to the solution

= \frac{2 ^{9 x - 3}}{9 ln ( 2 )} + C

24 x - 176

\int_{3}^{4} \frac{1}{( x - 3 ) ^{\frac{3}{2}}} d x

\int \frac{1}{1 - sin ( 5 x )} d x

\frac{d}{d x} (16 x sin (x))

\int \frac{1}{( 5 x + 3 ) ^{2}} d x
