9x exponent 5 over 3x exponent 9 (simplify the rational expression. If the rational expression cannot be simplified, so state)

Question

anonymous · Answer

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?
