You have 9x^5/3x^9. With problems like this where you just have differing exponents between the denominator and numerator, you subtract the exponents and leave whatever started at the smaller exponent as 1: 9x^5/3x^9 ... The top goes down to 0, since it has the smaller numerator, and the bottom's exponent loses 5, so it becomes 4: 9x^0/3x^4 9/3x^4 3/x^4 Does that make sense?
