展开 (sqrt(x)\circ x+8)(x)

解答

展开

(x \circ x + 8) (x)

\circ x^{2} x + 8 x

求解步骤

(x \circ x + 8) (x)

= (x) (\circ x x + 8)

使用分配律:

a (b + c) = ab + a c

a = (x), b = x \circ x, c = 8

= (x) x \circ x + (x) \cdot 8

= \circ (x) x x + 8 (x)

化简

\circ (x) x x + 8 (x) : \circ x^{2} x + 8 x

= \circ x^{2} x + 8 x

e x p an d (x^{2} sin (x) + 4 y) d y

e x p an d (4, - 1, 0) (8 x - 4 y + z + 9 = 0)

e x p an d \frac{3 Q ( 80000 - Q )}{2000}

e x p an d x^{3} (x^{3} + 2 x + 3)^{2} d x

e x p an d e^{2 x} (1 + e^{2 x})^{3} d x
