14. Several real math problems in the first year of junior high school 1. Given that X and y are real numbers, and (x - √ 3) & sup2; and | y + 3 | are opposite numbers, try to find the value of X-Y (the result can retain the root sign) 2. It is known that the decimal part of √ 15 is a and the decimal part of √ 15 is B. try to find the value of a + B 3. There is such a question: "find the value of X that makes the equation x · √ x-2009 = 0 tenable." If x · √ x-2009 = 0, then x = 0 or √ x-2009 = 0, that is, x = 0 or x = 2009. Therefore, when x = 0 or x = 2009, the original formula holds Do you think sloppy's answer is correct? If not, please write the correct answer Can you write down the process of solving the problem? thank you! ~
