integral of (3^{2+sqrt(x)}-5)/(sqrt(x))

\int \frac{3 ^{2 + x} - 5}{x} d x

\frac{18 \cdot 3 ^{x}}{ln ( 3 )} - 10 x + C

Solution steps

\int \frac{3 ^{2 + x} - 5}{x} d x

3^{2 + x} = 3^{2} \cdot 3^{x}

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

Expand

\frac{3 ^{2} \cdot 3 ^{x} - 5}{x} : \frac{9 \cdot 3 ^{x}}{x} - \frac{5}{x}

= \int \frac{9 \cdot 3 ^{x}}{x} - \frac{5}{x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{9 \cdot 3 ^{x}}{x} d x - \int \frac{5}{x} d x

\int \frac{9 \cdot 3 ^{x}}{x} d x = \frac{18 \cdot 3 ^{x}}{ln ( 3 )}

\int \frac{5}{x} d x = 10 x

= \frac{18 \cdot 3 ^{x}}{ln ( 3 )} - 10 x

Add a constant to the solution

= \frac{18 \cdot 3 ^{x}}{ln ( 3 )} - 10 x + C

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

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

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

\int 1 0^{9 x} d x

\int lo g_{x} (x^{2}) d x
