Explain in your own words, how to change a number written in scientific notation to standard notation.

Answer and step-by-step explanation:

In scientific notation, we have a decimal number multiplied by a power of 10.  The decimal number can have only one non-zero digit before the decimal point.  

The exponent of 10 tells us how many places to move the decimal; if it is negative, we move the decimal that many places to the left, making the number small.  If the exponent is positive, we move the decimal that many places to the right, making the number large.

We start from the decimal point and move it the correct number of places.
