Answer:


1.2E^(-9)

Explanation:

Jordan types 0.0000000012 into his calculator then presses Enter.

This can be shown as :


(1.2)/(1000000000)

Now, if this has to be written without fraction, the decimal will move 9 places to the left making it 0.0000000012.

If it has to be written in E form, then it becomes
1.2E^(-9)
