Q. 3n2=27 3 n^{2}=27 \newlineWhat are the solutions to the given equation?\newlineChoose 11 answer:\newline(A) n=3 n=\sqrt{3} \newline(B) n=3 n=3 \newline(C) n=3 n=-\sqrt{3} and n=3 n=\sqrt{3} \newline(D) n=3 n=-3 and n=3 n=3
  1. Isolate n2n^2: We have the equation 3n2=273n^2 = 27. To solve for nn, we first need to isolate n2n^2. We do this by dividing both sides of the equation by 33.\newlineCalculation: (3n2)/3=27/3(3n^2) / 3 = 27 / 3\newlinen2=9n^2 = 9
  2. Take square root: Now that we have n2=9n^2 = 9, we take the square root of both sides to solve for nn. Remember that taking the square root of a number gives us two solutions: one positive and one negative.\newlineCalculation: n2=±9\sqrt{n^2} = \pm\sqrt{9}\newlinen = ±3\pm3
