Question

Identify the numerical coefficients of terms (other than constants) in the following expressions:

(i) 5 − 3t² (ii) 1 + t + t² + t³ (iii) x + 2xy+ 3y

(iv) 100m + 1000n (v) − p²q² + 7pq (vi) 1.2a + 0.8b

(vii) 3.14 r² (viii) 2 (l + b) (ix) 0.1y + 0.01 y²

Answer 1

Row	Expression	Terms	Coefficients

(ii)	1 + t + t2 + t3	t t2 t3	1 1 1
(iii)	x + 2xy + 3y	x 2xy 3y	1 2 3
(iv)	100m + 1000n	100m 1000n	100 1000
(v)	− p2q2 + 7pq	− p2q2 7pq	− 1 7
(vi)	1.2a +0.8b	1.2a 0.8b	1.2 0.8
(vii)	3.14 r2	3.14 r2	3.14
(viii)	2(l + b)	2l 2b	2 2
(ix)	0.1y + 0.01y2	0.1y 0.01y2	0.1 0.01
