erweitern y^{1/4}(y^{3/4}+y^{7/4})

Lösung

erweitern

y^{\frac{1}{4}} (y^{\frac{3}{4}} + y^{\frac{7}{4}})

y + y^{2}

Schritte zur Lösung

y^{\frac{1}{4}} (y^{\frac{3}{4}} + y^{\frac{7}{4}})

Wende das Distributivgesetz an:

a (b + c) = ab + a c

y^{\frac{1}{4}} (y^{\frac{3}{4}} + y^{\frac{7}{4}}) = y^{\frac{1}{4}} y^{\frac{3}{4}} + y^{\frac{1}{4}} y^{\frac{7}{4}}

= y^{\frac{1}{4}} y^{\frac{3}{4}} + y^{\frac{1}{4}} y^{\frac{7}{4}}

y^{\frac{1}{4}} y^{\frac{3}{4}} = y

y^{\frac{1}{4}} y^{\frac{7}{4}} = y^{2}

= y + y^{2}

e x p an d \frac{2 \cdot ( x + y ) ^{2}}{3}

e x p an d \frac{( 2 x + 3 )}{( x - 2 ) ^{2}}

e x p an d (a sin (t) cos (p) - d sin (p))^{2}

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

e x p an d - \frac{6}{( x - 6 ) ^{2}}
