Work Step by Step
To convert from scientific notation to decimal notation, the first thing to look at is the sign of the exponent attached to the base number 10. If the sign is positive, move the decimal point over to the right as many times as the exponent indicates. If the sign is negative, move the decimal point over to the left as many times as the exponent indicates. Add zeros as place fillers until the location of the new decimal point is reached.
