Q. How do you write 730 in scientific notation?______×10______
Move Decimal Point: To write the number 730 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10. We do this by moving the decimal point in 730 so that there is only one non-zero digit to the left of the decimal point.
Rewrite Number: The number 730 can be rewritten as 7.30 by moving the decimal point two places to the left. This gives us the number between 1 and 10 that we need for scientific notation.
Multiply by Power: Since we moved the decimal point two places to the left, we must multiply 7.30 by 10 raised to the power of 2 to get back to the original number. This is because each move to the left increases the power of 10 by 1.
Scientific Notation: Therefore, 730 in scientific notation is written as 7.30×102.
