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 $= 2.3xx10^7$

$2.3*10^7$

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!
