- When you convert a number from decimal notation to scientific notation, how do you know if the exponent will be positive or negative?arrow_forwardThere are rules for converting numbers written in scientific notation to standard form and vice versa. Select all the rules below that correctly apply to scientific notation. When converting a standard number that is 10 or greater to scientific notation, move the decimal point to the left. A negative exponent in scientific notation means that the standard form of the number is greater than 10. When converting a standard number that is between 0 and 1 to scientific notation, move the decimal point to the right. A negative exponent in scientific notation means that the standard form of the number is between 0 and 1.arrow_forwardIn 2010, the U.S. population was 309.9 million and there were 128,900,000 American Facebook accounts.
