Answer :

For an expression, terms are the values that are separated by addition or substraction. And the coefficients are the values of term that are with the variables.

For example:

3 abc + 2 smk2 - 4 k is an expression.

So, the terms are 3 abc, 2 smk2 and -4k

And coefficients of these terms are : 3, 2, - 4


(i) Terms: 5xyz2 and -3zy


Coefficients: 5 and -3


(ii) Terms: 1, x and x2


Coefficients: 1, 1 and 1


(iii) Terms: 4x2y2, -4x2y2z2 and z2


Coefficients: 4, -4 and 1


(iv) Terms: 3, -pq, qr and -rp


Coefficients: 3, -1, 1 and -1


(v) Terms:


Coefficients:


(vi) Terms:


Coefficients:
