簡約 ((a 3/100 a[7])-a[10])*a[5]

解

簡約

((a \frac{3}{100} a [7]) - a [10]) \cdot a [5]

5 a (\frac{21 a ^{2}}{100} - 10 a)

解答ステップ

((a \frac{3}{100} a (7)) - a (10)) a (5)

規則を適用する:

(a) = a

(5) = 5

= (a \frac{3}{100} a \cdot 7 - a \cdot 10) a \cdot 5

簡素化

a \frac{3}{100} a \cdot 7 - a \cdot 10 : \frac{21 a ^{2}}{100} - 10 a

= (\frac{21 a ^{2}}{100} - 10 a) a \cdot 5

= 5 a (\frac{21 a ^{2}}{100} - 10 a)
