Chapter 11.5, Problem 50WE

To determine

To solve: $0=6n^2-0.42$ .

Answer to Problem 50WE

  $n=\pm 0.3$

Explanation of Solution

By using the property of square root as $x^2=\sqrt{a^2}$ implies $x=\pm a$ the given equation $0=6n^2-0.42$ can be simplified as

  $\begin{array}{l}{n}^2=\frac{0.42}{6}\\ n=\pm \sqrt{\frac{0.42}{6}}\\ n=\pm 0.3\end{array}$
