Answer:
144m^2*n^3
36m^3n
48m^4n^4
Step-by-step explanation:
I have 9m^2n=3^2m^2n and 16mn^3=2^4mn^3 as denominators
the least common denominator= 9*16*m^2*n^3=144m^2*n^3
I have 12mn=2^2*3mn and 18m^3n=2*3^2m^3n as denominators
the least common denominator=2^2*3^2m^3n=36m^3n
I have 24mn^4=2^3*3mn^4 and 16m^4n=2^4m^4n as denominators
the least common denominator=2^4*3m^4n^4=48m^4n^4
