36 is the square of 6; 100 is the square of 10; 121 is the square of 11. 71, 62, and 343 are not squares of whole numbers.
There is a trick to this one. cube the first and write it down. write the opposite sign of the middle term. multiply the first constant times the second constant times 2 and write it down. square the first term write it down, square the second term and write it down. cube the last term including its sign and write it down. Example: (a-b)^3= a^3+2a^2b^2-b^3 (2x+3y)^3=8x^3=12x^2y^2+27y^3
-- Write down a list of the first ten whole numbers. -- For each one, multiply it by itself, and write the product next to it.
2, 3, 5, 7, 11, 13
Then you write down both numbers
