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

0.000216 in scientific notation would be written as 2.16 x 10^-4. This is because when converting a decimal number to scientific notation, you move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. The number of places you moved the decimal point determines the exponent on 10. In this case, the decimal point was moved 4 places to the right, so the exponent is -4.

Answer 3

216
