... B: 2.23607
... C: 1.58114 . . . . matches the given expression in value
... D: 0.707107
_____
If you're familiar with the square roots of small integers, you can do this last exercise in your head once you have calculated 5/√10. That is, you can eliminate choices A, B, and D.
... √2 ≈ 1.414; √3 ≈ 1.732; √5 ≈ 2.236
228/12 = 19. To check, turn it into multiplication, by doing 19 * 12, which equals 228.
