Answer:
3d^2
Explanation:
First, find the GCF of 6 and 27, which is 3.
Factors of 6: 1, 2, 3, 6
Factors of 27: 1, 3, 9, 27
Then, find the greatest value of the variable d^3 and d^2, which is d^2. Since this is a variable, we just need to take out the highest degree accompanying the variable.
27(d^2)
6d(d^2)
Combine both of your findings to get 3d^2.
