Q. How do you write 720 in scientific notation?______×10______
Move Decimal Point: To write the number 720 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10. We can do this by moving the decimal point in 720 two places to the left, which gives us 7.20.
Determine Power of 10: Now that we have the number 7.20, which is between 1 and 10, we need to determine the power of 10 that will give us back the original number when multiplied by 7.20. Since we moved the decimal point two places to the left, we need to multiply 7.20 by 10 raised to the power of 2 to get back to the original number.
Write in Scientific Notation: Therefore, 720 in scientific notation is written as 7.20×102. This is because 7.20 multiplied by 102 (which is 100) equals 720.
