24x^515x^4/3x^2

Be careful with numerators and denominators and parentheses
What you wrote is
24x^5 (15x^4/3x^2)
but I bet what you mean is
(24x^515x^4)/3x^2
which is
24x^5/3x^2  15x^4/3x^2
or
8 x^3  5 x^2 
No the one I wrote is correct you divide by 3x^2 and there was no parentheses

ok if you really mean that.
I had a hunch it looked like
24x^515x^4

3x^2
but if you really mean
24 x^5  (15 x^4/3 x^2)
then
24 x^5  5 x^2 
It looks like the first one

Go with my original reply then. I had a hunch that was the case because both 24 and 15 were divisible by 3.

when you have more than one term in a numerator or denominator, put a parenthesis around them
a + b/c is just that , a alone plus b/c
but
(a+b) / c
is
a+b

c
or
a/c + b/c
