化简 (2.001-2)/(2.001^2-4)

解答

化简

\frac{2.001 - 2}{2.00 1 ^{2} - 4}

0.24993 \dots

求解步骤

\frac{2.001 - 2}{2.00 1 ^{2} - 4}

数字相减:

2.001 - 2 = 0.001

= \frac{0.001}{2.00 1 ^{2} - 4}

2.00 1^{2} - 4 = 0.004001

= \frac{0.001}{0.004001}

数字相除:

\frac{0.001}{0.004001} = 0.24993 \dots

= 0.24993 \dots
