integral of (5z^2-3)^3z

\int (5 z^{2} - 3)^{3} z d z

\frac{1}{40} (5 z^{2} - 3)^{4} + C

Solution steps

\int (5 z^{2} - 3)^{3} z d z

Apply u-substitution

= \int \frac{u ^{3}}{10} d u

Take the constant out:

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

= \frac{1}{10} \cdot \int u^{3} d u

Apply the Power Rule

= \frac{1}{10} \cdot \frac{u ^{4}}{4}

Substitute back

u = 5 z^{2} - 3

= \frac{1}{10} \cdot \frac{( 5 z ^{2} - 3 ) ^{4}}{4}

Simplify

\frac{1}{10} \cdot \frac{( 5 z ^{2} - 3 ) ^{4}}{4} : \frac{1}{40} (5 z^{2} - 3)^{4}

= \frac{1}{40} (5 z^{2} - 3)^{4}

Add a constant to the solution

= \frac{1}{40} (5 z^{2} - 3)^{4} + C
