Найдите сумму многочленов:

\(\displaystyle \left(7st^{\,2}+12stw^{\,2}+20st^{\,3}+5t^{\,4}w^{\,2}\right)+\left(50s^{\,4}t^{\,4}+24st^{\,2}+19stw^{\,2}+2st^{\,3}\right)=\)

\(\displaystyle =\)[ ]\(\displaystyle st^{\,2}\,+\)[ ]\(\displaystyle stw^{\,2}+\)[ ]\(\displaystyle st^{\,3}+5t^{\,4}w^{\,2}+50s^{\,4}t^{\,4}\)
