You can put this solution on YOUR website!
%28108r%5E2%2Ay%29%2F%289r%5E3%2Ay%5E2%29
First of all you need to cancel out 108 and 9;
%2812r%5E2%2Ay%29%2F%28r%5E3%2Ay%5E2%29
Now you subtract the exponents of the same variables;
12r%5E2r%5E-3%2Ay%5E1r%5E-2
12r%5E-1%2Ay%5E-1
since they are negative exponents they go in the denominator;
1%2F12ry
Hope you understand, it's kinda hard to explain negative exponents
