3 squared is 9, 5 squared is 25. So the product is 225.
It is 9
2 squared = 4 8 squared = 64 2 squared + 8 squared = 4 + 64 = 68 8 squared - 2 squared = 6 squared = 36 The product of 8 x 2 = 16.

A squared number is the product of an integer times itself. So, 16 is a squared number. 4 * 4 = 16.

second squared !

7 squared can be expressed as a product of the same factor by multiplying 7 by itself. Therefore, 7 squared can be written as 7 x 7.
As an example, the product of (a + b) (a - b) is equal to a squared - b squared."Special product" simply means that there are special cases, when multiplying polynomials, that are worth memorizing. For example, if you know the above, then you can easily start factoring any expression that contains the difference of two perfect squares - for example, x squared minus 1, a to the power 6 minus b to the power 4, or even - if you start using complex numbers - a squared + b squared = a squared - (-1) b squared.
