解答ステップ

(\frac{3}{2})^{2} - 3 (\frac{3}{2}) + 4

規則を適用する:

(a) = a

(\frac{3}{2}) = \frac{3}{2}

= (\frac{3}{2})^{2} - 3 \cdot \frac{3}{2} + 4

(\frac{3}{2})^{2} = \frac{9}{4}

3 \cdot \frac{3}{2} = \frac{9}{2}

= \frac{9}{4} - \frac{9}{2} + 4

\frac{9}{4} - \frac{9}{2} + 4 = \frac{7}{4}

= \frac{7}{4}
