化简 (12.9)/((s+1.1)(s+2))

解答

化简

\frac{12.9}{( s + 1.1 ) ( s + 2 )}

\frac{129}{10 ( s + 1.1 ) ( s + 2 )}

求解步骤

\frac{12.9}{( s + 1.1 ) ( s + 2 )}

小数点后有几位数字就乘以和除以几次 10。

小数点右侧有

1

位，因此乘以和除以

10

= \frac{10 \cdot 12.9}{10 ( s + 1.1 ) ( s + 2 )}

数字相乘:

10 \cdot 12.9 = 129

= \frac{129}{10 ( s + 1.1 ) ( s + 2 )}

s im pl i f y x^{3} (\frac{1}{x} - sin (\frac{1}{x}))

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

\frac{d}{d x} ((f (x, y)) (x + x^{2} - y^{2}))

e x p an d \frac{ab}{( sc + b ) ( s d + a )}

e x p an d (\frac{ln ( 6 x + 1 )}{x + 2} + \frac{6 ln ( 3 x + 6 )}{6 x + 1}) (3 x + 6)^{l n (6 x + 1)}
