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
