簡約 (1.1-2)/((1.1-1)^2)

解

簡約

\frac{1.1 - 2}{( 1.1 - 1 ) ^{2}}

- 90

解答ステップ

\frac{1.1 - 2}{( 1.1 - 1 ) ^{2}}

数を引く:

1.1 - 2 = - 0.9

= \frac{- 0.9}{( 1.1 - 1 ) ^{2}}

数を引く:

1.1 - 1 = 0.1

= \frac{- 0.9}{0. 1 ^{2}}

分数の規則を適用する:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{0.9}{0. 1 ^{2}}

0. 1^{2} = 0.01

= - \frac{0.9}{0.01}

数を割る:

\frac{0.9}{0.01} = 90

= - 90
