Question

How do you find the scientific notation for `151`?

Answer 1

`1.51 xx 10^2`

Explanation:

`151` is the same as `151color(red)(.0)`

To write this in proper scientific notation we should move the decimal point `color(red)(2)` places to the left which means this expression will have a positive exponent.

`151color(red)(.0) = 1.51 xx 10^2`
