Check here for instructional material to complete this problem. Write the number in standard form. Some event dates back to \( 3.7 \times 10^{9} \) years ago. \( 3.7 \times 10^{9}=\square \)

To convert the number \( 3.7 \times 10^{9} \) into standard form, simply move the decimal point in 3.7 nine places to the right. This gives you 3,700,000,000. So, the number in standard form is \( 3,700,000,000 \). Using scientific notation is incredibly useful in real-world applications, especially in fields like astronomy or geology where you're often dealing with very large or very small numbers. For example, the age of the Earth is estimated to be about \( 4.5 \times 10^{9} \) years, allowing scientists to easily communicate and manipulate these gigantic values without writing a string of zeros!
