#4.35886 xx 10^2#

This number is read as "four hundred" , then "and".

Scientific notation allows only one digit before the decimal place, and "hundred" is written mathematically as #10 xx 10#, or #10^2#.

Without the other digits, the number four hundred would be written as #4. xx 10^2#.

All the other digits in the number are written after the decimal point.

If you wrote #"3,000,000"# (three million) in scientific notation, write down the first digit and put in a decimal, #3.#

A million is #10 xx 10 xx 10 xx 10 xx 10 xx 10#, or #10^6#.

So you have #= 3. xx 10^6#

All other digits in the number are written after the decimal point.

#"3,173,765" -> 3.173 765 xx 10^6#
