One grain of sand weighs 0.0006write in standard form

The goal of writing a number in scientific notation is to have a decimal number, with one digit to the left of the decimal point, followed by a ×⨯1010 to some power. To format the number this way, multiply the 0.00060.0006 by 1010 −4-4 times, making it 66. Each multiplication by 1010 moves thedecimal point one digit to the left, but in order to keep the same number, multiply 66 by 10−410-4.6×10−4
