Hey there!
Numbers written in scientific notation are written in two parts.
First, we have the digits usually with a decimal. This number must be at least one and less than ten.
The second part is x 10 to a power. This power is the number of places the decimal has been moved.
To get a number at least one and less than 10, we would have to move the decimal place on this number 13 places to the left to get 5.928.
Because we move the decimal 13 places, the power of 10 is 13.
5.928 x 10¹³
Hope this helps!
