x^{2} + y^{2} (x^{2} + y^{2})

x^{2} x^{2} + y^{2} + y^{2} x^{2} + y^{2}

Schritte zur Lösung

x^{2} + y^{2} (x^{2} + y^{2})

Wende das Distributivgesetz an:

a (b + c) = ab + a c

x^{2} + y^{2} (x^{2} + y^{2}) = x^{2} + y^{2} x^{2} + x^{2} + y^{2} y^{2}

= x^{2} + y^{2} x^{2} + x^{2} + y^{2} y^{2}

= x^{2} x^{2} + y^{2} + y^{2} x^{2} + y^{2}

e x p an d (- cos (x) - sin (x)) (- sin (x) + cos (x) + 2)

e x p an d (3 x y^{2} - 4 y) + (3 x - 4 x^{2} y) y^{'} (x)

\frac{d ^{2}}{d x ^{2}} ((y) (- 5 x^{2} + 5 x))

e x p an d (6 e - 3 f - 4) 2

e x p an d (4 x y + 2 x sin (y)) d x + (2 x^{2} + x^{2} cos (y)) d y
