簡約 (5.01^2-5(5.01))/(5.01^2-25)

解

簡約

\frac{5.0 1 ^{2} - 5 ( 5.01 )}{5.0 1 ^{2} - 25}

0.50049 \dots

解答ステップ

\frac{5.0 1 ^{2} - 5 ( 5.01 )}{5.0 1 ^{2} - 25}

括弧を削除する:

(a) = a

= \frac{5.0 1 ^{2} - 5 \cdot 5.01}{5.0 1 ^{2} - 25}

5.0 1^{2} - 5 \cdot 5.01 = 0.0501

= \frac{0.0501}{5.0 1 ^{2} - 25}

5.0 1^{2} - 25 = 0.1001

= \frac{0.0501}{0.1001}

数を割る:

\frac{0.0501}{0.1001} = 0.50049 \dots

= 0.50049 \dots
