Explanation:
Add the exponents for common variables
[When exponents over the same variable are multiplying we ADD them]
So,
Now we move all of the negative exponents into a fraction as the denominator
[Remember everything has a 1 underneath it, we just don't write it because we know it is there]
Think of it like this
Now move the negative exponents to the denominator so that they become positive
[If there was a positive exponent it would stay in the numerator]
