There are two ways to do this. **Way 1:** Since 5.4 × 10^{7} = 0.054 × 10^{9},
we can rewrite the original problem as (0.054 × 10^{9}) + (3.23 × 10^{9}) which is 3.284 × 10^{9}. **Way 2: **Since 3.23 × 10^{9} = 323 × 10^{7},
we can rewrite the original problem as (5.4 × 10^{7}) + (323 × 10^{7}). This simplifies to 328.4 × 10^{7}, which in scientific notation is 3.284 × 10^{9}. |
