Question 3
Expend in exponential form by using the power of 10
(i) 172,
(ii) 5643

Answer 1

i) . 172 = 1 × $10^2$+ 7 × $10^1$ + 2 × $10^0$

ii) . 5643 = 5 × $10^3$ + 6 × $10^2$ + 4 × $10^1$ + 3 × $10^0$

Step-by-step explanation:

i) . We have,

172

To expand in the exponential form by using the power of 10 = ?

∴ 172

= 100 + 70 + 2

= 1 × $10^2$ + 7 × $10^1$ + 2 × $10^0$

ii) . We have,

5643

To expand in the exponential form by using the power of 10 = ?

∴ 5643

= 5000 + 600 + 40 + 3

= 5 × $10^3$ + 6 × $10^2$ + 4 × $10^1$ + 3 × $10^0$
