3

Solution steps

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

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{0}^{3}

Simplify

= [x]_{0}^{3}

Compute the boundaries:

3

= 3

\int_{3}^{4} 4 d x

\int_{3}^{5} e^{- x^{2}} x d x

\int_{0}^{1} (ln (1 + x)) d x

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

\int_{1}^{6} (\frac{3 x ^{2} + 2 x + 1}{x}) d x
