Final answer:
The correct standard form for the number 4.87 × 10⁶ is 4870000.
Step-by-step explanation:
The correct standard form for the number 4.87 × 10⁶ is option A) 4870000.
When a number is written in scientific notation, the part before the multiplication symbol (×) represents the significand, and the part after the multiplication symbol represents the power of 10.
In this case, the significand is 4.87 and the power of 10 is ⁶ (indicated by the exponent). To convert this number to standard form, you simply multiply the significand by 10 raised to the power of the exponent. Therefore, 4.87 × 10⁶ is equal to 4870000.
