développer x^{1/3}(x^2-21)

Solution

développer

x^{\frac{1}{3}} (x^{2} - 21)

x^{\frac{7}{3}} - x^{\frac{1}{3}} \cdot 21

étapes des solutions

x^{\frac{1}{3}} (x^{2} - 21)

Appliquer la loi de la distribution:

a (b - c) = ab - a c

x^{\frac{1}{3}} (x^{2} - 21) = x^{\frac{1}{3}} x^{2} - x^{\frac{1}{3}} \cdot 21

= x^{\frac{1}{3}} x^{2} - x^{\frac{1}{3}} \cdot 21

Simplifier

x^{\frac{1}{3}} x^{2} : x^{\frac{7}{3}}

= x^{\frac{7}{3}} - x^{\frac{1}{3}} \cdot 21

(x + y)^{2} d x + (2 x y + x^{2} - 1) d y

\frac{5}{2} + \frac{2 ( 4 2 - 2 )}{3}

\frac{\partial}{\partial x} ((z) (3 x z - z^{3} + yz))

(- 3 + i)^{8}

(sin (2 x) - cos (2 x))^{2}
