\frac{2 ( - 0.501 ) + 1}{\frac{1}{4} - ( - 0.50 1 ^{2} )}

- 0.003992008

Schritte zur Lösung

\frac{2 ( - 0.501 ) + 1}{\frac{1}{4} - ( - 0.50 1 ^{2} )}

Entferne die Klammern:

(- a) = - a, - (- a) = a

= \frac{- 2 \cdot 0.501 + 1}{\frac{1}{4} + 0.50 1 ^{2}}

- 2 \cdot 0.501 + 1 = - 0.002

= \frac{- 0.002}{\frac{1}{4} + 0.50 1 ^{2}}

0.50 1^{2} = 0.251001

= \frac{- 0.002}{\frac{1}{4} + 0.251001}

Wende Bruchregel an:

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

= - \frac{0.002}{\frac{1}{4} + 0.251001}

Wandle das Element in Dezimalform um

\frac{1}{4} = 0.25

= - \frac{0.002}{0.25 + 0.251001}

Addiere die Zahlen:

0.25 + 0.251001 = 0.501001

= - \frac{0.002}{0.501001}

Teile die Zahlen:

\frac{0.002}{0.501001} = 0.003992008

= - 0.003992008

5 (2 x - 3) + 8 = 9

∣ 3 a + 5 ∣ = ∣ 4 a - 7 ∣

- 4 x \leq - 16

7 x - 1 = 8 x - 14

10 x - 4.5 + 3 x = 12 x - 1.1
