Q. How do you write 700,000 in scientific notation?______×10______
Express in Scientific Notation: To write a number 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 the number to the left until only one non-zero digit remains to the left of the decimal point. The number of places we move the decimal point will be the exponent of 10.
Move Decimal Point:700,000 has five zeros following the 7, so we move the decimal point 5 places to the left to get 7.00000.
Identify Number: After moving the decimal point 5 places to the left, we get 7.0, which is the number between 1 and 10 that we will use in the scientific notation.
Determine Exponent: Since we moved the decimal point 5 places, the exponent of 10 will be 5. Therefore, 700,000 in scientific notation is written as 7.0×105.
