Найдите суммы одночленов:

\(\displaystyle 17x^{\,2}y^{\,7}z+21x^{\,2}y^{\,7}z=\)	[ ]\(\displaystyle x^{\,2}y^{\,7}z,\)
\(\displaystyle 101s^{\,10}t^{\,8}+ (-62)s^{\,10}t^{\,8}=\)	[ ]\(\displaystyle s^{\,10}t^{\,8},\)
\(\displaystyle (-13)u^{\,7}w^{\,6}v+ 7u^{\,7}w^{\,6}v=\)	[ ]\(\displaystyle u^{\,7}w^{\,6}v,\)
\(\displaystyle (-27)s^{\,4}w^{\,2}t^{\,7}+ (-93)s^{\,4}w^{\,2}t^{\,7}=\)	[ ]\(\displaystyle s^{\,4}w^{\,2}t^{\,7}.\)
