integral from 9 to 25 of 1/(sqrt(x))

\int_{9}^{25} \frac{1}{x} d x

4

Solution steps

\int_{9}^{25} \frac{1}{x} d x

Apply the Power Rule

: [2 x^{\frac{1}{2}}]_{9}^{25}

= [2 x^{\frac{1}{2}}]_{9}^{25}

Apply radical rule:

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

= [2 x]_{9}^{25}

Compute the boundaries:

4

= 4

\int_{2}^{4} x^{5} d x

\int_{1}^{e^{9}} \frac{1}{x ( 1 + ln ( x ) )} d x

\int_{- 1}^{0} (2 x + x^{2} - x^{3}) d x

\int_{0}^{1} 1 0^{3 x} + 1 0^{- 3 x} d x

\int_{0}^{10} ln (x) d x
