$hey \: mate \: \\ \\ 1.there \: is \: only \: \: one \: variable \: x \: \\ it \: is \: polynomial \: in \: one \: variable \: x \: { \: yes \: this \: is \: a \: polynomial \: in \: one \: variable \: x} \: \\ \\ 2.this \: expression \: is \: a \: polynomial \: in \: one \: variable \: y \\ 3.at \: the \: power \: of \: t \: is \: \frac{1}{2} which \: is \: not \: a \: whole \: no. \: hence \: this \: expression \: is \: not \: a \: polynomial \: \\ \\ 4.power \: of \: y \: is \: 1 \: and \: - 1 \: since \: - 1 \: is \: not \: a \: whole \: no. \: this \: is \: not \: polynomial \: \\ \\ 5.all \: power \: are \: whole \: no. \: it \: is \: a \: polynomial$
