Its alright, You are doing better than a whole bunch of people
you know why?
because you realized you needed help and asked.
Now, aside from mushy pep talk, let me help you a bit.
When multiplying numbers with exponents, its the same as adding the exponents so \(x^{2} * x^{3} = x^{5}\)
cool right?
now you can take your answer \(\frac{ x^{5} y^{10}}{ x^{9} y^{5}}\)
Remember though, if you don't see the exponent, it is 1, not zero.
so if you noticed, \(x * x^{8} = x^{9}\)
just remember that and you should be fine
also, if you have to simplify more, and example would be \(\frac{ x^{2} }{x} = x\)
you get that from subtracting the \(x^{1}\) from the top \(x^{2}\)
BUT
if it is \(\frac{ x^{2} y^{2} }{ x^{2}}\) YOU DO NOTHING this is because that \(x^{2}\) on the top is being multiplied by \(y^{2}\), which means it changes the equations value
