| Expression | x=4 | x=1/9 |
| x + √x | 4 + √4 = 4 + 2 = 6 | 1/9 + √(1/9) = 1/9 + 1/3 = 1/9 + 3/9 = 4/9 |
| x - √x | 4 - √4 = 4 - 2 = 2 | 1/9 - √(1/9) = 1/9 - 1/3 = 1/9 - 3/9 = -2/9 |
| x√x | 4√4 = 4 * 2 = 8 | (1/9)√(1/9) = (1/9) * (1/3) = 1/27 |
| √x/x | √4/4 = 2/4 = 1/2 | √(1/9)/(1/9) = (1/3)/(1/9) = (1/3) * 9 = 3 |
| x/√x | 4/√4 = 4/2 = 2 | (1/9)/√(1/9) = (1/9)/(1/3) = (1/9) * 3 = 1/3 |
