Best ResponseYou've already chosen the best response.1Lemme break down the first denominator a sec, maybe we can see what's going on.\[\Large\rm 50x^4y^3=25\cdot2 x^1 x^3y^1y^2=\color{orangered}{25xy^2}\cdot2x^3y\]

Best ResponseYou've already chosen the best response.1So I broke down the first denominator so that it contains the second denoinator (orange) and a little bit more.

Best ResponseYou've already chosen the best response.1To get your LCM, you would multiply the second fraction by 2x^3y. That would finish things up for you. So it looks like the LCM is just going to be that whole bottom left side since it contains the right denominator, and more.
