Question

How do you write `1.91 times 10^-3` in standard notation?

Answer 1

`1.91xx10^-3 = 0.00191`

Explanation:

Standard notation is a number simply written with numeric digits.

`10^-3` can be written `0.001`, therefore

`1.91xx10^-3` can be written `1.91xx0.001`.

Multiplying `1.91" by "0.001` yields 0.00191.

I hope this helps,
