integral of (5\times 2^x)/(3^x)

\int \frac{5 \cdot 2 ^{x}}{3 ^{x}} d x

\frac{5 \cdot 2 ^{x}}{ln ( \frac{2}{3} ) \cdot 3 ^{x}} + C

Solution steps

\int \frac{5 \cdot 2 ^{x}}{3 ^{x}} d x

Take the constant out:

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

= 5 \cdot \int \frac{2 ^{x}}{3 ^{x}} d x

Apply exponent rule:

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

= 5 \cdot \int (\frac{2}{3})^{x} d x

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

= 5 \cdot \frac{( \frac{2}{3} ) ^{x}}{ln ( \frac{2}{3} )}

Simplify

5 \cdot \frac{( \frac{2}{3} ) ^{x}}{ln ( \frac{2}{3} )} : \frac{5 \cdot 2 ^{x}}{ln ( \frac{2}{3} ) \cdot 3 ^{x}}

= \frac{5 \cdot 2 ^{x}}{ln ( \frac{2}{3} ) \cdot 3 ^{x}}

Add a constant to the solution

= \frac{5 \cdot 2 ^{x}}{ln ( \frac{2}{3} ) \cdot 3 ^{x}} + C

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

\int (1 - sin (2 x))^{2} d x

\int \frac{2 t - 1}{( t + 1 ) ^{3}} d t

\int 2 x a^{2} - x^{2} d x

\int sinh (x) + cosh (x) d x
