Teori

$Udda n : (- a)^{n} = - a^{n}$

Sätter man en udda exponent på ett negativt tal blir potensen negativ. Vi kan därför plocka bort parentesen. Exempelvis betyder $(- 3)^{5}$ att $- 3$ multipliceras fem gånger. Två minustecken tar ut varandra, så minustecknen tar ut varandra parvis.

(- 3)^{5}

$(- a) (- b) = a \cdot b$

3 \cdot 3 \cdot 3 \cdot 3 \cdot (- 3)

$a (- b) = - a \cdot b$

- 3 \cdot 3 \cdot 3 \cdot 3 \cdot 3

Skriv som potens

- 3^{5}
