Use Law of Exponents for Product. In symbol: %28x%5Em%29%28x%5En%29=x%5E%28m%2Bn%29, you add the exponent when multiplying expressions with the same base.
In your answer, you applied the other rule which is the Law of Exponents for Power. In symbol: %28x%5Em%29%5En+=+x%5E%28mn%29.
The correct answer using the Law of Exponents for product is highlight%28-20x%5E7y%5E5%29
