展开 bc+d+d!(b+!c)(ad+b)

解答

展开

b c + d + d! (b +! c) (a d + b)

b c + d +! b c d a d! +! b^{2} c d!

求解步骤

b c + d + d! (b +! c) (a d + b)

= b c + d + d! (+! b c) (d a + b)

乘开

d! (b +! c) (a d + b) :! b c d a d! +! b^{2} c d!

= b c + d +! b c d a d! +! b^{2} c d!

\frac{d}{d x} ((t) (- k (t - 4)))

e x p an d \frac{100000 ( s + 10 )}{s + 5}

e x p an d 8 (x + Δ x)^{2} - 8 x

e x p an d 5 (x + y) - 4 (3 x - 2 y = 1)

e x p an d 9.8 - 3.21
