integral from 2 to 5 of 2/x

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

2 (ln (5) - ln (2))

Decimal

1.83258 \dots

Solution steps

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

Take the constant out:

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

= 2 \cdot \int_{2}^{5} \frac{1}{x} d x

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= 2 [ln ∣ x ∣]_{2}^{5}

Compute the boundaries:

ln (5) - ln (2)

= 2 (ln (5) - ln (2))
