Question

How do you write `0.03054` in scientific notation?

Answer 1

`3.054 \times 10^{-2}`

Explanation:

Writing numbers in scientific notation means moving the decimal point left or right so that the number is between `1` and `10`.

In the number `0.03054`, you need to move the decimal point two places to the right to get to `3.054` (which is between 1 and 10).

Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied `3.054` by `10^{-2}`. Think about it: `3.054 \times 10^{-2} = 0.03054`. In other words, you are kind of writing equivalence statements.
