Answer:

C. ±4/5

Explanation:

Given the equation

[tex]25x^2=16[/tex]

The first step is to divide both sides by 25 to isolate the variable x.

[tex]\begin{gathered} \frac{25x^2}{25}=\frac{16}{25} \\ x^2=\frac{16}{25} \end{gathered}[/tex]

Next, we take the square roots of both sides of the equation.

[tex]\begin{gathered} \sqrt{x^2}=\pm\sqrt{\frac{16}{25}} \\ x=\pm\frac{4}{5} \end{gathered}[/tex]

The correct choice is C.
