Scientific notation is used to shorten the amount of zeros you have to write out for a number.
To take a number out of scientific notation, move the decimal a number of times equal to the exponent: in my example it would be 3. If the exponent is positive, move the decimal to the right; if it is negative, move the decimal to the left.
First, multiply the decimal numbers using what you have learned about decimal multiplication. Next, multiply the powers of 10 by adding their exponents. Now, combine the results. Finally, convert your answer to scientific notation.
