Question

How do you write 23,000,000 in scientific notation?

Answer 1

Normalized scientific notation is in the form:
`axx10^n`
`a` is a value `>=0` and `<10`
and `n` is an integer

Since
`23,000,000 = 23xx1000,000`
or `2.3 xx 10,000,000`
and
since
`10,000,000 = 10^7`

`23,000,000` in normalized scientific notation `= 2.3xx10^7`

Answer 2

`2.3*10^7`

Explanation:

The key realization is that when we write numbers in scientific notation, we want one digit before the decimal point.

In our case, we must loop it `7` times to the left. The number of times we loop it is our exponent, and looping left makes it positive. Thus, we have

`2.3*10^7`

Hope this helps!
