Question

$v^{2} = \frac{25}{81}$Hi my question is it says Find the solution(s) of the following equation. I attached the possible answers. Do you think you can help me?

Answer 1

C, and D

1) We're told that the original equation is:

$v^2=\frac{25}{81}$

2) Then let's calculate it taking the square root on both sides:

$\begin{gathered} \sqrt[]{v^2}=\pm\sqrt[]{\frac{25}{81}} \\ v=-\frac{5}{9},\text{ }\frac{5}{9} \end{gathered}$

3) So we can state that the answer is C, and D
