109 = 9 + 100
The difference of two squares is equivalent to the sum, times the difference, of the numbers that are squared. In symbols: a2 - b2 = (a + b)(a - b) Here is an example with numbers: 102 - 92 = (10+9)(10-9)
1 squared = 1 2 squared = 4 3 squared = 9 4 squared = 16 5 squared = 25 6 squared = 36 7 squared = 49 8 squared = 64 9 squared = 81 10 squared = 100
9
seven 4 x 4 = 16 3 x 3 = 9 16 - 9 = 7
90
33 = 3x3x3 = 9 22 = 2x2 = 4 The difference between them is 5 (9-4).
Sure thing, honey. The square numbers between 50 and 90 are 64 (8 squared), 81 (9 squared), and 100 (10 squared). Hope that helps, sweetie.
