Lesson Steps
| Steps | Problem | Solution |
|---|---|---|
1 |
Simplify |
\$ (1 1/2)^3 × (2 2/3)^2 ÷ (4 5/4)^1 \$ |
2 |
After simplification we get |
\$ (3/2)^3 × (8/2)^2 ÷ (21/5)^1 \$ |
3 |
After simplification we get |
\$ 3^3/2^3 × 8^2/2^2 ÷ (21/5) \$ |
4 |
After simplification we get |
\$ 27/8 × 64/4 ÷ (21/5) \$ |
5 |
By using BODMAS rule |
\$ (\cancel27^9) / (\cancel8^1) × (\cancel64^8)/(4) × (5)/(\cancel21^7) \$ |
6 |
After cancellation we get |
\$ 9 × \cancel8^2/\cancel4^1 × 5/7 \$ |
7 |
After cancellation we get |
\$ 9 × 2 × 5/7 \$ |
8 |
After simplification we get |
\$ 90/7 \$ |
9 |
Answer |
