i) . 172 = 1 × + 7 × + 2 ×
ii) . 5643 = 5 × + 6 × + 4 × + 3 ×
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 × + 7 × + 2 ×
ii) . We have,
5643
To expand in the exponential form by using the power of 10 = ?
∴ 5643
= 5000 + 600 + 40 + 3
= 5 × + 6 × + 4 × + 3 ×
