Question

find the lcm of a^3 b^4,ab^5 and a^2b^7​

Answer 1

Answer:

a³b⁷

Step-by-step explanation:

a³ = a x a x a

b⁴ = b x b x b x b

ab⁵ = a x b x b x b x b x b

a²b⁷ = a x a x b x b x b x b x b x b x b

in these, a³ has the most a(s) and a²b⁷ has the most b(s).

therefore, their L.C.M. is a³b⁷
