化简 (3x+5^{-1}\circ 4x)(x)

解答

化简

(3 x + 5^{- 1} \circ 4 x) (x)

x (3 x + \frac{4 \circ x}{5})

求解步骤

(3 x + 5^{- 1} \circ 4 x) (x)

去除括号:

(a) = a

= (3 x + 5^{- 1} \circ 4 x) x

5^{- 1} \circ 4 x = \frac{4 \circ x}{5}

= x (3 x + \frac{4 \circ x}{5})

e x p an d \frac{- 6 t - 1}{( 6 t - 5 ) ( t + 8 )}

e x p an d \frac{2 + x}{2 x ( x + 1 )}

e x p an d 1 n (\frac{e ^{5}}{7})

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

e x p an d A (1, 2) B (3, - 1)
