After identifying the powers of 10 for the starting prefix and target prefix, what is the next step in converting metric system units using Approach 1?

A) Add the starting value to 10?x, where ?x is the product of the powers of 10.
B) Divide the starting value by 10?x, where ?x is the sum of the powers of 10.
C) Multiply the starting value by 10?x, where ?x is the difference between the powers of 10.
D) Raise the starting value to the power of 10?x, where ?x is the dividend of the powers of 10.
