Given

`0.002403`

Required

Express as scientific notation

The rule of scientific notation is that:

It is represented in form of:
`a * 10^n` where
`1 \le a \le 10`

`0.002403` will be represented as: a = 2.403; notice that the point was shifted forward by 3 units.

So:

n = -3

The equation becomes:

`a * 10^n`

`0.002403`
`= 2.403 * 10^(-3)`

Approximate

`0.002403`
`= 2.4 * 10^(-3)`
