What is the square root of 12?
3.464
Well, that's true, but you could simplify it in radicals. The square root of 12 is the same as saying the square root of 3 times the square root of 4. The square root of 4 is plus or minus 2, so you could say (I wish I had a square root symbol)
+/- 2 the square root of 3 and that's the same answer.
