integral of e^{x+7}

\int e^{x + 7} d x

e^{7 + x} + C

Solution steps

\int e^{x + 7} d x

e^{x + 7} = e^{7} e^{x}

= \int e^{7} e^{x} d x

Take the constant out:

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

= e^{7} \cdot \int e^{x} d x

Use the common integral:

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

= e^{7} e^{x}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

e^{7} e^{x} = e^{7 + x}

= e^{7 + x}

Add a constant to the solution

= e^{7 + x} + C

\frac{\partial}{\partial x} (ln (x^{4}))

\frac{15}{s ^{2} + 2 s + 5}

\int \frac{1}{cos ^{2} ( θ ) 1 + tan ( θ )} d θ

\frac{d x}{d t} = a - b x

y = (5 - 3 x^{2})^{3}
