Answer:
Erica
Step-by-step explanation:
The given expression is
.
The prime factorization of the first term is

The prime factorization of the second term is

The greatest common factor is product of the least powers of the common factors.

Therefore Erica is correct.
Answer:
-3/2
Step-by-step explanation:
Because 3 is on the postive side and 2 is on the negative
sqrt 7 ( sqrt 14 + sqrt 3 )
distribute
sqrt(7) sqrt(14) +sqrt(7) *sqrt(3)
sqrt(98) + sqrt(21)
sqrt(49*2) + sqrt(21)
sqrt(49) * sqrt(2) + sqrt(21)
7sqrt(2) + sqrt(21)
