integral from 1 to e^4 of 1/(x(1+ln(x)))

\int_{1}^{e^{4}} \frac{1}{x ( 1 + ln ( x ) )} d x

ln (5)

Decimal Notation

1.60943 \dots

Solution steps

\int_{1}^{e^{4}} \frac{1}{x ( 1 + ln ( x ) )} d x

Apply u-substitution

: \int_{1}^{5} \frac{1}{u} d u

= \int_{1}^{5} \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= [ln ∣ u ∣]_{1}^{5}

Compute the boundaries:

ln (5)

= ln (5)

\int y^{2} \cdot cos (y) d y

\int \frac{5}{2 x - 2} d x

(1 + x^{6}) \frac{d y}{d x} = \frac{x ^{5}}{y}

\int_{0}^{4} \frac{e ^{x}}{x} d x

x \to 1 + lim (\frac{x}{ln ( x )})
