Question

What is 0.00089 in scientific notation?

Answer 1

`0.89`x`10^-3`
`890`x`10^-6`

Explanation:

`0.00089` is simply `0.00089`x`10^0`

`10^0` is equal to `1`

To change this to scientific notation, the decimal is moved from left to right.

For example, `10^-6` means you move the decimal place six places to the right. `10^-9` means moving the decimal point nine spaces to the right.

If the power was `10^12` then you do the opposite and move the decimal twelve places to the left which would make your value larger whereas a negative power signifies a small value tending to zero.

If you use a scientific calculator, the ENG button will do this for you (if you have one).
