9w² and 12w⁴
9w² = 3*3w²
12w⁴ = 3*4*w⁴
To create Least common multiple we need
1) all numbers, and if they are repeating more than one time, we take largest number of repetitions (we have 2 repetitions of 3 in 9, so we will take 3*3)
So, for number part 3*3*4 = 36
2) For letter part, we will take the letter with the highest exponent. So, we will take w⁴.
3) Final answer is 3*3*3*4w⁴ = 36w⁴
