Lesson Steps
| Steps | Problem | Solution |
|---|---|---|
1 |
Evaluate the expression |
\$ (100 × 5^-2)(25 × 10^-3) \$ |
2 |
Converting to exponents if possible |
\$ (10^2 × 5^-2)(5^2 × 10^-3) \$ |
3 |
After simplification we get |
\$ (10^2/5^2) (5^2/10^3) \$ |
4 |
After Eliminating the brackets we get |
\$ \cancel(10^2)/\cancel(5^2) × \cancel(5^2)/(\cancel((10^2))10^1) \$ |
5 |
After cancellation we get |
\$ 1/10 \$ |
6 |
Answer |
