化简 8.8(a+b) 2/c-05+(29)/((9+y))(a+b)(1/h)

解答

化简

8.8 (a + b) \frac{2}{c} - 0 \cdot 5 + \frac{29}{( 9 + y )} (a + b) \cdot (\frac{1}{h})

\frac{17.6 ( a + b )}{c} + \frac{29 ( a + b )}{( 9 + y ) h}

求解步骤

8.8 (a + b) \frac{2}{c} - 0 \cdot 5 + \frac{29}{9 + y} (a + b) (\frac{1}{h})

使用法则:

(a) = a

(\frac{1}{h}) = \frac{1}{h}

= 8.8 (a + b) \frac{2}{c} - 0 \cdot 5 + \frac{29}{9 + y} (a + b) \frac{1}{h}

8.8 (a + b) \frac{2}{c} = \frac{17.6 ( a + b )}{c}

0 \cdot 5 = 0

\frac{29}{9 + y} (a + b) \frac{1}{h} = \frac{29 ( a + b )}{( 9 + y ) h}

= \frac{17.6 ( a + b )}{c} - 0 + \frac{29 ( a + b )}{( 9 + y ) h}

合并

\frac{17.6 ( a + b )}{c} - 0 + \frac{29 ( a + b )}{( 9 + y ) h} : \frac{17.6 ( a + b )}{c} + \frac{29 ( a + b )}{( 9 + y ) h}

= \frac{17.6 ( a + b )}{c} + \frac{29 ( a + b )}{( 9 + y ) h}
