9 squared is another way of stating the equation 9 X 9, and 10 squared is another way of stating the equation 10 X 10. Find the answers to these equations, add them together, and you will have the answer.

10

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).

When 100 is squared, the root is 10. That means you can multiply 10 by 10 and the answer is 100. The square root of 81 is 9 and 8 is the square root of 64.
