Yes, 8100 = 90^2. As to if you want to know why. Maybe you just want to see how you can tell. A number a2b2 will equal (ab)2. So if any two perfect squares are multiplied together, the product is also a perfect square. With a = 9, and b = 10, then you have a2 = 81, and b2 = 100. And a2b2 = (ab)2 = 8100.
