For this problem, you don't have to evaluate exact numbers, but just enough to get an understanding for which one is larger to save time.

Quantity A: $$3(2^5)$$
Quantity B: $$5(3^2)$$

Quantity A: $$3(32)$$
Quantity B: $$5(9)$$

Quantity A: $$3(32)$$
Quantity B: $$45$$

**At this point, you can see that 3 * 32 = some number bigger than 45. You don't need to calculate it to find the exact number, however you can just to be sure.

Quantity A: $$96$$
Quantity B: $$45$$

Quantity A is bigger than Quantity B.
The answer is A.

The answer is A.

You did calculate almost the whole number though. Re: 3(2^5)   [#permalink] 19 Jun 2018, 23:28
