展開する (1/2-(sqrt(3))/2)^{16}

解

展開する

(\frac{1}{2} - \frac{3}{2})^{16}

解

\frac{18817}{256} - \frac{679 3}{16}

+1

十進法表記

1.03796 E - 7

解答ステップ

(\frac{1}{2} - \frac{3}{2})^{16}

2項定理を適用する:

(a + b)^{n} = i = 0 \sum n (i n) a^{(n - i)} b^{i}

a = \frac{1}{2}, b = - \frac{3}{2}

= i = 0 \sum 16 (i 16) (\frac{1}{2})^{(16 - i)} (- \frac{3}{2})^{i}
