Answer:
(x+y)²
Explanation:
Given the expressions (x + y) and (x + y)².
We are to find the LCM of (x + y) and (x + y)²
Taking the factors as shown
(x+y ) || (x + y) (x + y)²
(x+y ) || 1 (x+y)
|| 1 1
Multiplying both factors to get the LCM
= (x+y)(x+y)
= (x+y)²
Hence the LCM of (x + y) and (x + y)² is (x+y)²
