Final answer:
To express the distance from Mars to Earth (in kilometers) in standard form, we can use scientific notation. The given distance is 2.25 x 10^8 kilometers. In standard form, the distance is 225,000,000 kilometers.
Step-by-step explanation:
The question asks to express the distance from Mars to Earth, which is given as 2.25 x 108 kilometers, in standard form. To convert scientific notation to standard form, you multiply the base number by 10 raised to the power indicated. Here's the step-by-step calculation or To express the distance from Mars to Earth (in kilometers) in standard form, we can use scientific notation. The given distance is 2.25 x 10^8 kilometers. In standard form, we move the decimal point 8 places to the left. Therefore, the distance is 225,000,000 kilometers.
