展開する A(2, 3/4)B(3/5 ,-1/2)

解

展開する

A (2, \frac{3}{4}) B (\frac{3}{5}, - \frac{1}{2})

\frac{3}{5} (2 \cdot \frac{3}{4},) A B, - \frac{1}{2} (2 \cdot \frac{3}{4},) A B

解答ステップ

A (2, \frac{3}{4}) B (\frac{3}{5}, - \frac{1}{2})

= (2 \cdot \frac{3}{4},) (\frac{3}{5}, - \frac{1}{2}) A B

分配法則を適用する:

a (b - c) = ab - a c

a = A (2, \frac{3}{4}) B, b = \frac{3}{5},, c = \frac{1}{2}

= A (2, \frac{3}{4}) B \frac{3}{5}, - A (2, \frac{3}{4}) B \frac{1}{2}

= \frac{3}{5} (2 \cdot \frac{3}{4},) A B, - \frac{1}{2} (2 \cdot \frac{3}{4},) A B
