Задание

Найдите сумму многочленов:

\(\displaystyle \left(9xy^{\,2}z+13xz^{\,3}+5xy+17x^{\,2}y^{\,2}z^{\,2}\right)+\left(21x^{\,3}y^{\,3}+17xy^{\,2}z+31xz^{\,3}+41xy\,\right)=\)

\(\displaystyle =\)[ ]\(\displaystyle xy^{\,2}z\,+\)[ ]\(\displaystyle xz^{\,3}+\)[ ]\(\displaystyle xy+17x^{\,2}y^{\,2}z^{\,2}+21x^{\,3}y^{\,3}\)
