Question

How do you write 0.283 x 10^-1 in scientific notation?

Answer 1

In (normalized) scientific notation
`0.283xx10^(-1) = 2.83xx10^(-2)`

Explanation:

Normalized scientific notation has one non-zero digit to the left of the decimal point.
Moving the decimal point from `0.283` to `2.83` requires that we multiply `0.283` by `10^1`
Equivalently `2.83` must be divided by `10^1` (or multiplied by `10^(-1)`) to equal `0.283`

So `0.283xx10^(-1) = (2.83xx10^(-1))xx10^(-1)`
`color(white)("XXXXXXXXXXXX")=2.83xx10^(-2)`
