11.2 million in standard scientific notation?

Answer 1

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.
