$\int_{0}^{1} (x^{15} + 15^{x}) d x$

Step 1

Remove parentheses.

$\int_{0}^{1} x^{15} + 15^{x} d x$

Step 2

Split the single integral into multiple integrals.

$\int_{0}^{1} x^{15} d x + \int_{0}^{1} 15^{x} d x$

Step 3

By the Power Rule, the integral of $x^{15}$ with respect to $x$ is $\frac{1}{16} x^{16}$ .

$\frac{1}{16} x^{16}]_{0}^{1} + \int_{0}^{1} 15^{x} d x$

Step 4

The integral of $15^{x}$ with respect to $x$ is $\frac{15^{x}}{\ln (15)}$ .

$\frac{1}{16} x^{16}]_{0}^{1} + \frac{15^{x}}{\ln (15)}]_{0}^{1}$

Step 5.2.2.1

One to any power is one.

$\frac{1}{16} \cdot 1 + \frac{15^{1}}{\ln (15)} - (\frac{1}{16} \cdot 0^{16} + \frac{15^{0}}{\ln (15)})$

Step 5.2.2.2

Multiply $\frac{1}{16}$ by $1$ .

$\frac{1}{16} + \frac{15^{1}}{\ln (15)} - (\frac{1}{16} \cdot 0^{16} + \frac{15^{0}}{\ln (15)})$

Step 5.2.2.3

Evaluate the exponent.

$\frac{1}{16} + \frac{15}{\ln (15)} - (\frac{1}{16} \cdot 0^{16} + \frac{15^{0}}{\ln (15)})$

Step 5.2.2.4

Raising $0$ to any positive power yields $0$ .

$\frac{1}{16} + \frac{15}{\ln (15)} - (\frac{1}{16} \cdot 0 + \frac{15^{0}}{\ln (15)})$

Step 5.2.2.5

Multiply $\frac{1}{16}$ by $0$ .

$\frac{1}{16} + \frac{15}{\ln (15)} - (0 + \frac{15^{0}}{\ln (15)})$

Step 5.2.2.6

Anything raised to $0$ is $1$ .

$\frac{1}{16} + \frac{15}{\ln (15)} - (0 + \frac{1}{\ln (15)})$

Step 5.2.2.7

Add $0$ and $\frac{1}{\ln (15)}$ .

$\frac{1}{16} + \frac{15}{\ln (15)} - \frac{1}{\ln (15)}$

Step 5.2.2.8

Combine the numerators over the common denominator.

$\frac{1}{16} + \frac{15 - 1}{\ln (15)}$

Step 5.2.2.9

Subtract $1$ from $15$ .

$\frac{1}{16} + \frac{14}{\ln (15)}$

Step 6

The result can be shown in multiple forms.

Exact Form:

$\frac{1}{16} + \frac{14}{\ln (15)}$

Decimal Form:

$5.23227122 \dots$
