解

簡約

\frac{5.00 1 ^{2} - 5 ( 5.001 )}{5.00 1 ^{2} - 25}

0.50004 \dots

解答ステップ

\frac{5.00 1 ^{2} - 5 ( 5.001 )}{5.00 1 ^{2} - 25}

括弧を削除する:

(a) = a

= \frac{5.00 1 ^{2} - 5 \cdot 5.001}{5.00 1 ^{2} - 25}

5.00 1^{2} - 5 \cdot 5.001 = 0.005001

= \frac{0.005001}{5.00 1 ^{2} - 25}

5.00 1^{2} - 25 = 0.010001

= \frac{0.005001}{0.010001}

数を割る:

\frac{0.005001}{0.010001} = 0.50004 \dots

= 0.50004 \dots
