化简 5x(\sqrt[3]{x^2y})+2(\sqrt[3]{x^5y})

解答

化简

5 x (3 x^{2} y) + 2 (3 x^{5} y)

5 x 3 x^{2} y + 2 x 3 x^{2} 3 y

求解步骤

5 x (3 x^{2} y) + 2 (3 x^{5} y)

5 x (3 x^{2} y) = 5 x 3 x^{2} y

2 (3 x^{5} y) = 2 x 3 x^{2} 3 y

= 5 x 3 x^{2} y + 2 x 3 x^{2} 3 y

\frac{6}{11} = 3 x^{2}

5 x^{2} + 20 x = - 35

3 x - 12 - 9 = 2 - x + 5

s im pl i f y lo g_{4} (8) + lo g_{4} (5)

- 29 = 5 x + 6 - 12 x
