The speed of light is \( 3 \times 10^{5} \) kilometers per second. What is that in standard form? \( \begin{array}{l}150 \\ 3,00003 \\ 3,000,000 \\ 300,000\end{array} \)

To express the speed of light, which is given as \( 3 \times 10^{5} \) kilometers per second, in standard form, we need to convert it into a numerical value. The expression \( 3 \times 10^{5} \) means that we take the number 3 and move the decimal point 5 places to the right. Let's perform the calculation step by step: 1. Start with the number 3.0. 2. Move the decimal point 5 places to the right: - 1st place: 30 - 2nd place: 300 - 3rd place: 3000 - 4th place: 30000 - 5th place: 300000 Thus, \( 3 \times 10^{5} = 300000 \). Now, let's compare this with the options provided: - \( 150 \) - \( 3,00003 \) - \( 3,000,000 \) - \( 300,000 \) The correct answer in standard form is \( 300,000 \).
