What is 20 in scientific notation?

----------------------------------------------------------------------------------------------------------------------------

20 = 20.0

Move the decimal so that only one non-zero digit is to its left.

Thus, we have

2.0      Then, multiply this times 10 raised to a positive exponent indicating the number of places the decimal was moved.  So we have

2.0 x 10

Moving the decimal to the left is indicated by a positive exponent. Moving it to the right results in a negative exponent.
