integral from 1 to 9 of (6/(sqrt(x)))

\int_{1}^{9} (\frac{6}{x}) d x

24

Solution steps

\int_{1}^{9} \frac{6}{x} d x

Take the constant out:

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

= 6 \cdot \int_{1}^{9} \frac{1}{x} d x

Apply the Power Rule

: [2 x^{\frac{1}{2}}]_{1}^{9}

= 6 [2 x^{\frac{1}{2}}]_{1}^{9}

Apply radical rule:

a^{\frac{1}{n}} = n a

= 6 [2 x]_{1}^{9}

Compute the boundaries:

4

= 6 \cdot 4

Simplify

= 24

\int_{- 9}^{- 2} - \frac{3}{( x + 3 ) ^{2}} d x

\int_{0}^{2} 9 d x

\int_{0}^{\frac{π}{3}} sec (θ) d θ

\int_{- 1}^{2} \frac{1}{x ^{2} - 4} d x

\int_{1}^{x^{4}} sec (x) d x
