Question

What is the product of 877 and 0.345 expressed to the correct significant digits and written in proper scientific notation?

Answer 1

`3.03 * 10^2`

Explanation:

Both numbers, `807` and `0.345` have 3 significant digits .

Since they are multiplying, you must consider the answer to have the lowest number of significant digits, which, in this case, happens to be `3`.

Therefore,

`807 * 0.345`
`=302.56500`
`=3.03 * 10^2`

NOTE
It's `3.03` rather than `3.02` as you must round the last digit, which was `2` in this case. Since a `56` was followed by it, it must be rounded up.
