integral from 2 to infinity of 3/(x^4)

\int_{2}^{\infty} \frac{3}{x ^{4}} d x

\frac{1}{8}

Decimal

0.125

Solution steps

\int_{2}^{\infty} \frac{3}{x ^{4}} d x

Compute the indefinite integral:

\int \frac{3}{x ^{4}} d x = - \frac{1}{x ^{3}} + C

Compute the boundaries:

\int_{2}^{\infty} \frac{3}{x ^{4}} d x = 0 - (- \frac{1}{8})

= 0 - (- \frac{1}{8})

Simplify

= \frac{1}{8}

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

\int_{1}^{2} \frac{1 + x ^{2}}{x ^{2}} d x

\int_{1}^{e} \frac{( t ^{6} + 1 )}{t} d t

\int_{1}^{2} (6 - 5 x)^{4} d x

\int_{3}^{15} \frac{1}{x} d x
