4.17 x 10^-3
The first number (4.17) must be between or equal to 1.0 and 9.9. Cannot be lower than 1.0 and cannot be 10.0. Move the decimal between the 4 and 1 to make a number in this range and count the decimal places that it took you get there; that becomes your exponent. In this case it's a negative exponent.
Another example would be kind of like the reverse with a positive exponent 4170 = 4.17 x 10^3
