integral of (10x)^n

\int (10 x)^{n} d x

\frac{1 0 ^{n} x ^{n + 1}}{n + 1} + C

Solution steps

\int (10 x)^{n} d x

Simplify

(10 x)^{n} : 1 0^{n} x^{n}

= \int 1 0^{n} x^{n} d x

Take the constant out:

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

= 1 0^{n} \cdot \int x^{n} d x

Apply the Power Rule

= 1 0^{n} \cdot \frac{x ^{n + 1}}{n + 1}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 0 ^{n} x ^{n + 1}}{n + 1}

Add a constant to the solution

= \frac{1 0 ^{n} x ^{n + 1}}{n + 1} + C
