integral from 1 to 7 of 6/(x^4)

\int_{1}^{7} \frac{6}{x ^{4}} d x

\frac{684}{343}

Decimal Notation

1.99416 \dots

Solution steps

\int_{1}^{7} \frac{6}{x ^{4}} d x

Take the constant out:

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

= 6 \cdot \int_{1}^{7} \frac{1}{x ^{4}} d x

Apply the Power Rule

: [- \frac{1}{3 x ^{3}}]_{1}^{7}

= 6 [- \frac{1}{3 x ^{3}}]_{1}^{7}

Compute the boundaries:

\frac{114}{343}

= 6 \cdot \frac{114}{343}

Simplify

= \frac{684}{343}

\int_{0}^{π} 2 \cdot sin (x) d x

\int_{0}^{2 π} 5 x 2 d x

\int_{- 8}^{64} \frac{1}{x ^{\frac{1}{3}}} d x

\int_{0}^{12} \frac{1}{3} ln (t + 1) d t

\int_{0}^{\frac{π}{2}} e^{- t} cos (t) d t
