Identify the greater number, in each of the following.(a) 26 or 62(b)

1.	Identify the greater number, in each of the following.(a) 26 or 62(b) 29 or 92(c) 7.9 x 104 or 5.28 x 105
Answer» (a) We have, 2⁶= 2 x 2 x 2 x 2 x 2 x 2 = 64 and 6² = 6 x 6 = 36 So, 2⁶ > 6² (b) We have, 2⁹ = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512 and 9² = 9 x 9 = 81 So, 2⁹ > 9² (c) We have, 7.9 x 10⁴ = 7.9 x 10000 = 79000 and 5.28 x 10⁵ = 5.28 x 100000 = 528000 So, 5.28 x 10⁵ > 7.9 x 10⁴

Identify the greater number, in each of the following.(a) 26 or 62(b) 29 or 92(c) 7.9 x 104 or 5.28 x 105

Answer»

(a) We have, 2⁶= 2 x 2 x 2 x 2 x 2 x 2 = 64 and 6² = 6 x 6 = 36 So, 2⁶ > 6²

(b) We have, 2⁹ = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512 and 9² = 9 x 9 = 81

So, 2⁹ > 9²

(c) We have, 7.9 x 10⁴

= 7.9 x 10000 = 79000 and 5.28 x 10⁵ = 5.28 x 100000 = 528000

So, 5.28 x 10⁵ > 7.9 x 10⁴
