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#

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!
