To do:

We have to identify the terms and their coefficients for the given expressions.

Solution:

(i) $7x^2yz - 5xy$

 Term Coefficient $7x^2yz$ $7$ $-5xy$ $-5$

(ii) $x^2 + x + 1$

 Term Coefficient $x^2$ $1$ $x$ $1$ $1$ $1$

(iii) $3x^2y^2 - 5x^2y^2z^2 + z^2 + 1$

 Term Coefficient $3x^2y^2$ $3$ $-5x^2y^2z^2$ $-5$ $z^2$ $1$ $1$ $1$
(iv) $9- ab + be-ca$
 Term Coefficient $9$ $9$ $-ab$ $-1$ $be$ $1$ $-ca$ $-1$
(v) $\frac{a}{2}+\frac{b}{2}-ab$
 Term Coefficient $\frac{a}{2}$ $\frac{1}{2}$ $\frac{b}{2}$ $\frac{1}{2}$ $-ab$ $-1$
(vi) $2x - 0.3xy + 0.5y$
 Term Coefficient $2x$ $2$ $-0.3xy$ $-0.3$ $0.5y$ $.0.5$
