Solve the equation. Write all apparent solutions. Which of them are extraneous? $\sqrt { b } = 5$

Question

Quizplus · Accepted Answer

The equation is solved by squaring both sides:
$$\sqrt{b} = 5$$
$$(\sqrt{b})^2 = 5^2$$
$$b = 25$$
Therefore, the apparent solution is $b=25$. There are no extraneous solutions, since both sides of the original equation are non-negative. Therefore, the best choice is C: 25, there are no extraneous solutions.
