Solving for the square root of (40/2) will result in a different answer from solving for (the square root of 40) / 2. 40/2 = 20 20^½ ≈ ±4.472 40^½ ≈ ±6.325 ±6.325 ÷ 2 ≈ ±3.162
No. Square numbers are from numbers being squared like 2 squared is 4. Squaring a number is multiplying it by itself so 3x3=9, 4x4=16, 5x5=25, and so on. The closest square numbers to 40 are 36 (6x6) and 49 (7x7) there are no whole numbers to square in between 6 and 7 so 40 cannot be a square number

The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
Numbers are x, x +2 and x + 4 x (x+2) = (x+4)^2 - 40 x^2 + 2x = x^2 + 8x + 16 - 40 2x - 8x = 16 - 40 -6x = -24 x = 4 Numbers are 4, 6 and 8 Check: 4 x 6 = 24, 8^2 - 40 = 64 - 40 = 24 QED
The common factors of 28 and 40 are 1, 2 and 4.
