To calculate scientific notation, first identify the non-zero digits of the number. Move the decimal point to create a new number between 1 and 10. Count the number of places the decimal has moved; this becomes the exponent, with a base of 10. If you moved the decimal to the left, the exponent is positive; if to the right, it's negative. The final notation is the new number times 10 raised to the exponent. For example, 4500 becomes 4.5 x 10^3.
FAQs & Answers
- What is scientific notation used for? Scientific notation is used to express very large or very small numbers in a compact form, making them easier to read, write, and calculate.
- How do you convert a number to scientific notation? To convert a number to scientific notation, move the decimal point to create a number between 1 and 10, then multiply by 10 raised to the number of decimal places moved.
- What does a negative exponent in scientific notation mean? A negative exponent indicates that the decimal point was moved to the right, representing a number smaller than 1.
