correct: A
(0.82)^2 * (0.82)^3 = (0.82)^5 and (0.82)^6 is less than (0.82) because 0.82 is less than 1 and any number morever multiplied by a number than 1, will reduce.
A is bigger than B.

Answer is A (as the power goes up, quantity reduces as its below 1 decimal)

We can solve this question using matching operations
Given:
Quantity A: $$(0.82)^2 (0.82)^3$$
Quantity B: $$(0.82)^6$$

Simplify Quantity A to get:
Quantity A: (0.82)^5
Quantity B: (0.82)^6

Divide both quantities (0.82)^5 to get:
Quantity A: 1
Quantity B: (0.82)^1

In other words:
Quantity A: 1
Quantity B: 0.82
