Change the order of multiplication to make it easier, multiply the non-powers first. and then simplify the powers of 10. Remember, multiplying by a negative changes the sign of the product. It's all about using exponent properties to simplify the product. video https://cdn.kastatic.org/googleusercontent/le3-nXSZe0WFyh7KdUUmI1Xrd_ijiY3NefvLOdAXZYwZ60AcsD_j4Mqdv5EEsWThqW7yLVRG6WuvcCeFdLgb59Pf7w Multiplying multiples of powers of 10 Let's multiply (9 * 10^9) (-2 * 10^-3) using the power of exponents!

We can use division and powers of 10 to get a sense of just how many times as large the world population was. Is there really such a big difference between 10 to the 8th and 10 to the 9th? You bet there is! video https://cdn.kastatic.org/googleusercontent/h402XpORUasAIlTGpVj_7oIauTlNGKCvZTCE6d4BZvxFP71y-JGTSVe_WqMGK69veQ5mRFaAGiE3YcqCSuIHVvk Approximating with powers of 10 How much larger was the world population than the US population in 2014?
