Explanation

We are given the following equation:


x^2=(144)/(81)

We are required to solve the given equation.

This is achieved thus:


\begin{gathered} x^2=(144)/(81) \\ \text{ Square root both sides} \\ √(x^2)=\pm\sqrt{(144)/(81)} \\ x=\pm(12)/(9) \\ \text{ Upon simplification, we have:} \\ x=\pm(4)/(3) \end{gathered}

Hence, the answer is:


x=\operatorname{\pm}(4)/(3)

The first option is correct.
