Taking perfect squares out of square roots. - Khan Academy …
Web2 and 10. 4 and 5. Well 4 is a perfect square, so now we can think of sqrt (20) like this: sqrt (4*5) We haven't changed the value under the square root sign, we just broke 20 apart. Since the square root of 4 is 2, we can now write the answer as: 2*sqrt (5) We took the 4 out of the root and made it a 2 since we know what the square root of 4 is. WebYes, square roots can create 2 answers -- the positive (principal) root and the negative root. When you are working with square roots in an expression, you need to know which value you are expected to use. The default is the principal root. We only use the negative root when there is a minus in front of the radical. For example: 8 + sqrt (9) = 11. how do you cook tempeh
