integral of (12)/(x^4)

\int \frac{12}{x ^{4}} d x

- \frac{4}{x ^{3}} + C

Solution steps

\int \frac{12}{x ^{4}} d x

Take the constant out:

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

= 12 \cdot \int \frac{1}{x ^{4}} d x

Apply the Power Rule

: - \frac{1}{3 x ^{3}}

= 12 (- \frac{1}{3 x ^{3}})

Simplify

12 (- \frac{1}{3 x ^{3}}) : - \frac{4}{x ^{3}}

= - \frac{4}{x ^{3}}

Add a constant to the solution

= - \frac{4}{x ^{3}} + C

arctan (\frac{x}{2})

\frac{d y}{d x} - 50 y = - y^{2}

\int_{2}^{x} \frac{1}{8} (x - 2) d x

n = 1 \sum \infty (- 6)^{n} x^{n}

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