What is 0.000216 in scientific notation?

Answer 1

move the decimal point so that you only have one significant number (greater than 0) to the left of it. in this case you would move it to make it 2.16 Next, count how many places you moved (4). In order to get back to the original number, the decimal needs to be moved backward 4 places (making the places moved -4). Each number moves a value of 10 (in other words, to get from 2.16 to 21.6 you multiply by 10)

so the scientific notation of 0.000216 would be 2.16 x 10^-4

Answer 2

216
