Best ResponseYou've already chosen the best response.2We only use \(\pm\) when we "induce the" square root. \(\sqrt{4}=2\) \(x^2=4\implies x=\pm 2\) @dan815

Best ResponseYou've already chosen the best response.0I used the prime factorization of 4560 2*2*2*2*3*5*19 took the 2's out 4*15=60 and 4*19= 76 I know the root will be between 60 and 76 76 60 =16 1915 = 4 for every change by 1 number the root changes by 4 the average change is 2 so the root changes by 2*4 = 8 the square root is therefore 60 +8 = 68
