A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.


QUANTITY A: (5)(3²) + (3²)(2)
Factor out the 3² to get: 3²(5 + 2)
Evaluate to get: 3²(7)
We can see that 3² is the largest power of 3 that is a factor of (5)(3²) + (3²)(2)

QUANTITY B: (3)(2) + (7)(3)
Factor out the 3 to get: 3(2 + 7)
Evaluate to get: 3(9)
Evaluate to get: 27
Rewrite as: 3³
We can see that 3³ is the largest power of 3 that is a factor of (3)(2) + (7)(3)

3³ is greater than 3²
Answer: B

Cheers,
Brent
