Express the number in scientific notation.


(Use the multiplication symbol in the math palette as needed.)

To express in scientific notation, you need to move the decimal point to the left until only one non-zero digit is to the left of the decimal. Here, the number becomes after moving the decimal 9 places left. Thus, it is written as:

It’s like packing a suitcase! You condense all those big numbers into a neat, manageable form that’s both easier to work with and more efficient for communication.

When using scientific notation, it’s essential to remember that the exponent tells you how many places to move the decimal. If you ever mix it up, just ask yourself whether the original number is big or small—if it’s big, you’ll have a positive exponent like , but for small numbers, the exponent will be negative.
