There would be 35 commas, with the first one being after the 21.
456*105 = 45 600 000, that is 456 followed by 5 zeros.
Count the zeros. 5 zeros = 105
5 if you write it out. only 1 if you write it as " 1 x 105 " .
5.3 X 105 ============the zeros are superfluous
6.048 X 105 ========= The zeros are superfluous
5 x 21 = 105
300000000 (8 zeros) = 300,000,000 m = 3.0 x 108 m = 3.0 x 105 km
105
(105) / (102) = 103 = 1,000(100,000) / (100) = 1,000I would just like to add that using powers of ten is a good way to show how the exponent rules work: When you multiply numbers with like bases, you add the exponents: bx * by = b(x+y), so if you have: 103 * 102 = 105 , so103 = 1000 (one with 3 zeros), 102 = 100 (one with 2 zeros), and 105 = 100,000 (one with 5 zeros). Multiplying by 100 can be accomplished by move the decimal point to the right 2 places.In division (like bases remember), you subtract exponents, so (105) / (102) = (105-2) = 103 = 1000. So dividing by (102, which is 100) is the same as moving the decimal point to the left, 2 places.
In words, you'd write it as one hundred and five million. You'd write the number as 105,000,000. A number in the hundreds has 3 digits, a number in the thousands has 4-6 digits, and a number in the millions has 7-9 digits. A written out number with the word million after it denotes that six zeros would follow behind that number, as such: 105,000,000. If a written out number had the word thousand after it, that would mean that number should be followed by 3 zeros: i.e. 25,000.
105 meters = ~344.5 feet
