1. The problem is to write the number 5,430,000 in scientific notation. 2. Scientific notation expresses numbers as a product of a number between 1 and 10 and a power of 10. 3. To convert 5,430,000, move the decimal point 6 places to the left to get 5.43. 4. This corresponds to multiplying by 10 raised to the power of 6. 5. Therefore, the scientific notation is $$5.43 \times 10^{6}$$. 6. Note that the exponent 6 indicates how many places the decimal point was moved to the left.
