Найдите суммы одночленов:

\(\displaystyle 12x^{\,7}+71x^{\,7}=\)	[ ]\(\displaystyle x^{\,7}\)
\(\displaystyle 101y^{\,13}+ (-31)y^{\,13}=\)	[ ]\(\displaystyle y^{\,13}\)
\(\displaystyle (-25)z^{\,71}+ 14z^{\,71}=\)	[ ]\(\displaystyle z^{\,71}\)
\(\displaystyle (-13)u^{\,3}+ (-12)u^{\,3}=\)	[ ]\(\displaystyle u^{\,3}\)
