Question

Explain the steps for writing 0.000000001in scientific notation.

Answer 1

First, you move the decimal to the right until the decimal is 1 unit to the left of the decimal point which is then followed by a x10 to some power. In this equation, it would move 9 spaces to the right. there fore it would be 1x10 and since the decimal goes 9 spaces to the right it will be to the power of -9. So the scientific notation would look like 1 x 10^-9

Answer 2

scientific notation is
n*10ᵇ
where
1≤n<10 and b is how many spaces you moved the decimal to the left, if you moved it to the right, make b negative

0.000000001 to
1.000000000
9 spaces
to the right so negative

1*10⁻⁹ is answer
