To change a number in scientific notation to standard

form, reverse the process.  Move the decimal to make

 is larger if the exponent is positive.  Move the decimal

to make it smaller if the exponent is negative. 

Remember a negative exponent is a faction/decimal.

 

3.88 x 102 becomes 388 because the decimal moved

two places to make it a larger number.
