If a = 2 and b = 5, what is (ab)^2?

Explanation:
Squaring a product means you square each factor: (ab)^2 = a^2 b^2. With a = 2 and b = 5, you get a^2 = 4 and b^2 = 25, and multiplying them gives 4 × 25 = 100. Alternatively, ab = 2 × 5 = 10, and then 10^2 = 100. So the result is 100. The other numbers come from squaring only one factor or not squaring the product at all.
