What is the "shortcut" when writing powers of 10 from standard form to exponential form?

• move the decimal point to the right if it is less than 1
• move the decimal point to the left if it is more than 1
• the number of zeros matches the exponent number (less than 1 = negative, more than 1 = positive)
• all of these choices are the "shortcut"!
