There is no such thing as scientific digits. There are 6 digits in the number of which 3 are SIGNIFICANT (not scientific) digits.
There are three significant digits. I am not sure what scientific digits are!
One digit
Yes they are, if they are large numbers. You do not need to count how many digits there are.
In scientific notation that number would be written as 7.080 x 10-3 and it would have four significant digits.
It is: 6,500,000 or as6.5*107 in scientific notation

There is no way to know how many significant digits are in 33000. If you are forced to choose then there are 2 significant digits but, again, there is really no way to tell. If the count of significant digits is important, the number should be expressed in scientific notation.

The "fancy" name for fingers and toes is digits.

Because less digits are needed in scientific notation to represent very large numbers.
If you want to have it in standard format, only one.
Just the one digit from 1 to 9
One: no more and no fewer. And it cannot be a zero.
11,200,000 in scientific notation is 1.12 x 107 because to write scientific notation you simply put a decimal after the first digit so you have 1.1200000, then you drop the zeroes, to give you 1.12, and then you multiply it or x it by 10 to the power of how many digits follow the first number, so 11,200,000I bolded the digits after the 1st digit, and the commas do not count because they are not digits. so if you count the digits, there are 7, so you put 107 as the multiplier for 1.12, so the full standard scientific notation would read 1.12 x 107.
