Solution

(i) Co-efficient of $7 x^{2} y z = 7$

co-efficient of $- 5 x y = - 5$

(ii) Co-efficient of $x^{2} = 1$

co-efficient of $x = 1$

co-efficient of $1 = 1$

(iii) Co-efficient of $3 x^{2} y^{2} = 3$

co-efficient of $- 5 x^{2} y^{2} z^{2} = - 5$

co-efficient of $z^{2} = 1$

(iv) Co-efficient of $9 = 9$

co-efficient of $- a b = - 1$

co-efficient of $b c = 1$
