integral of \sqrt[7]{tan(8x)}sec^2(8x)

\frac{7}{64} tan^{\frac{8}{7}} (8 x) + C

Solution steps

Apply u-substitution

= \int \frac{7 u ^{7}}{8} d u

Take the constant out:

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

= \frac{7}{8} \cdot \int u^{7} d u

Apply the Power Rule

= \frac{7}{8} \cdot \frac{u ^{8}}{8}

Substitute back

Simplify

= \frac{7}{64} tan^{\frac{8}{7}} (8 x)

Add a constant to the solution

= \frac{7}{64} tan^{\frac{8}{7}} (8 x) + C
