the highest one is 20x20 =400 all you have to do is find the answers to from 1x1 to 19x19 that is only 19 little calculations good luck
The square of 400 is (400 \times 400 = 160,000). Therefore, 100 times the square of 400 is (100 \times 160,000 = 16,000,000).
No, 325 is not a perfect square however 324 is a perfect square.

2020^2 = 400400 is a perfect square.......perfect square  noun Mathematics .1.a rational number that is equal to the square of another rational number.2.a polynomial that is the square of another polynomial.Origin:1935-40
400 can be factored as 24 * 52, or 22 * 22 * 52. A perfect square factor of 400 will always have an even exponent, so here is a list: 12, 22, 42, 52, 102, and 202.
If the value applied in the radical is not a perfect square, it is irrational. 25; 400; and 625 are perfect squares and are rational when applied in a radical.
