You can put this solution on YOUR website!
Since you're only looking for the lowest common denominator, focus only on x%5E3y and xy%5E4
Look for the maximum exponent for the variables x and y from both denominators
The maximum for x= x%5E3
The maximum for y= y%5E4
combine it and your final answer is x%5E3Y%5E4
