6 Write the following in scientific notation: a) \( 5,235,000,000 \)

To write \( 5,235,000,000 \) in scientific notation, you move the decimal point 9 places to the left, giving you \( 5.235 \times 10^9 \). This format makes it easier to handle very large numbers and is favored in fields like science and engineering. When dealing with scientific notation, always remember to keep the coefficient (the number before the multiplication) between 1 and 10. It’s a handy trick that simplifies calculations and comparisons—especially when you’re working with calculations that involve both large and small numbers!
