Question

question 1 (10 points)
the universe is extremely vast and still expanding - how can we keep track of those large numbers? what is something they have developed to help scientists? please explain in three or more complete sentences.

Explanation:

Scientists use scientific notation to handle large numbers. Scientific notation expresses a number as \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer. For example, the distance from the Earth to the Sun is about \(150000000\) kilometers, which can be written as \(1.5\times 10^{8}\) kilometers in scientific notation. This simplifies calculations and makes it easier to compare and understand magnitudes of large quantities in astronomy and other scientific fields.

Answer:

Scientists use scientific notation. It simplifies large - number representation (\(a\times10^{n}\), \(1\leqslant|a|\lt10\)), aids calculations (e.g., distance to Sun \(1.5\times 10^{8}\) km), and enhances comparison of magnitudes.
