What is the scientific notation for a lenth of 0.000028?

It’s the millionth i think idk how to say it

2.8×10^ -5
Scientific notation is found by finding a number between 1 up to 9.9 (but not 10).

eg. 2.8 ( place à dot in between the number and count back to the original dot)
0.00002.8 (it moves 5 times)
Use ×10 to indicate the position (No of 0's)
if you move to the left, the power is -
If you move to the right, the power is +

Therefore 2.8×10^-5
