Best ResponseYou've already chosen the best response.1\(2\pm \dfrac{\sqrt{36}}{6}\) \(2\pm \dfrac{6}{6}\) OK, what is next?

Best ResponseYou've already chosen the best response.1I am assuming the first... but you might have meant: \(\dfrac{2\pm \sqrt{36}}{6}\) It is a little unclear which by how it is written. 2±√(36)/6 = \(2\pm \dfrac{\sqrt{36}}{6}\) (2±√36)/6 = \(\dfrac{2\pm \sqrt{36}}{6}\) In either case, the first thing is getting thr square root of 36, which is 6.

Best ResponseYou've already chosen the best response.1It is simplification. Order of operations. PEMDAS Parenthesis Exponents Multiplication and Division Addition and Subtraction Now, the square root is related to exponents, so pretty high up there.

Best ResponseYou've already chosen the best response.11+2*3 Because of the order of operations, I multiply first: 1+6 7 But if it was: (1+2)*3 The paren make the addition happen first: 3*3 9 The order changes the answer. That is why it is a key concept. All this question is saying is that you need to use the order of operations to simplify the result. So the only other issue is exactly how it is written, which changes it a lot.
