vereinfachen (sqrt(a))(asqrt(b)-bsqrt(a))

Lösung

vereinfachen

(a) (a b - b a)

a a b - ab

Schritte zur Lösung

(a) (a b - b a)

Apply rule:

(a) = a

(a) = a

= a (a b - b a)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a (a b - b a) = a a b - a b a

= a a b - a b a

a a b = a a b

- a b a = - ab

= a a b - ab
