Answer
- Quantity A is greater
Quantity A is greater. Using the order of operations, the expression for Quantity A can be solved as follows:
\(8^{2}-3\left(4+5\times 2\right)\)
\(64-3\left(14\right)=64-42=22\)
Using the order of operations, the expression for Quantity B can be solved as follows:
\(\left(\sqrt{81}-\sqrt{49}\right)\times \left(72\div 9\right)\)
\(\left(9-7\right)\times \left(8\right)\)
\(2\times 8=16\)
Compare Quantity A and Quantity B and select one of the following four answer choices.
The least common multiple of 12 and 16
The least common multiple of 24 and 3
- Quantity A is greater.
- Quantity B is greater.
- The two quantities are equal.
- The relationship cannot be determined from the information given.
