簡約

((2 x) (0.898))^{2} (x (0.66))

2.12890656 x^{3}

解答ステップ

((2 x) (0.898))^{2} (x (0.66))

簡素化

((2 x) (0.898))^{2} : 3.225616 x^{2}

= 3.225616 x^{2} x \cdot 0.66

数を乗じる:

3.225616 \cdot 0.66 = 2.12890656

= 2.12890656 x^{2} x

指数の規則を適用する:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x = x^{2 + 1}

= 2.12890656 x^{2 + 1}

数を足す:

2 + 1 = 3

= 2.12890656 x^{3}
