Find (3 × 10^{4})(5 × 10^{2}). Write the answer in scientific notation.

Since multiplication can be done in any order, we can rewrite this as (3 × 5)(10^{4} × 10^{2}). It makes our lives easier that multiplication has the versatility of Tom Hanks. We can then simplify to 15 × 10^{6}, which in scientific notation is 1.5 × 10^{7}. Houston, we don't have a problem. Aw yeah.
