Question
solve $27=(x - 7)^2$, where $x$ is a real number. round your answer to the nearest hundredth. if there is more than one solution, separate them with commas. if there is no solution, click on
o solution\.
Step1: Tomar raíz cuadrada
Tomamos la raíz cuadrada de ambos lados de la ecuación \(27 = (x - 7)^2\). Entonces, \(x - 7=\pm\sqrt{27}\). Simplificamos \(\sqrt{27}\) como \(3\sqrt{3}\approx5.196\).
Step2: Resolver para x
Para la solución positiva: \(x - 7 = \sqrt{27}\approx5.196\), entonces \(x = 7 + 5.196 = 12.196\approx12.20\) (redondeado a la centésima). Para la solución negativa: \(x - 7 = -\sqrt{27}\approx - 5.196\), entonces \(x = 7-5.196 = 1.804\approx1.80\) (redondeado a la centésima).
