Question -
Answer -
(i) m –2
Putting m = 2, we get
2 – 2 = 0
(ii) 3m – 5
Putting m = 2, we get
3 × 2 – 5 = 6 – 5 = 1
(iii) 9 – 5m
Putting m = 2, we get
9 – 5 × 2 = 9 – 10 = -1
(iv) 3m2 – 2m – 7Putting m = 2, we get
3(2)2 – 2(2) – 7 = 3 × 4 – 4 – 7
=12 – 4 – 7 = 12 – 11 = 1
(v) 5m/2−4
Putting m = 2, we get
(5×2)/2−4=5−4=1
