What is 142.00 written in scientific notation?

Answer 1

Well since 142 is too big for Scientific notation, we would make it into a number above 1 and less than 10. So to do this, we would take 142 and slide the decimal over 2 places to the left, making it 1.42. So since we made moved it over to the left 2 places, we need to put it in scientific notation. Since we are moving the decimal to the left, we need to make it 102. Then the finished equation would be 1.42x102.
