Answer:
6.7 x 10^3 = 6700
7.31 x 10^6 = 7310000
Step-by-step explanation:
These are clearly in scientific notation. To change them back to standard form, a good rule of thumb is to think of the exponent as how many times you need to "move" the decimal to the right. So if you have 1.0 x 10^8, you will then need to "move" the decimal 8 spaces to the right. (10000000) Technically speaking the decimal is now at the end of the number.
