expand (x^2+y^2)*sqrt(x^2+y^2)

expand

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

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

Solution steps

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

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

Apply the distributive law:

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}
