Question

What is 0.00000000472 estimated as the product of a single digit and a power of 10?

Answer 1

move the decimal point over to the right til it's between the 4 and the 7. The object of scientific notation is to end up with a number that's greater than 0 but less than 10. Because the original number is less than 1, when you move the decimal to the right, the power on the 10 is to the negative. 4.72 x 10^-9
