Answer:
Let's say you wanted to count the stars in the night sky and there are many star in the sky and that number is going to be hard to remember but with the scientific notation it will be shorter. A light year is the distance that light can travel in a year, or about 6 trillion (6,000,000,000,000) miles. As this example shows, numbers in science may be very large. Many other numbers in science are very small. Both very large and very small numbers have many zeroes, so they are hard to read and write without making mistakes. That’s where scientific notation comes in. Scientific notation is a way of writing very large or very small numbers that uses exponents. Numbers are written in a format like this a*10^b
The letter a stands for a decimal number, and the letter b stands for an exponent, or power, of 10. For example, the number 300 is written in scientific notation as 3.0 × 102. The number 0.03 is written as 3.0 × 10-2. It’s easier to convert numbers to and from scientific notation than you might think.
