Question

Diego thinks that x = 3 is a solution to the equation x² = 16. Do you agree?Explain or show your reasoning. *Yes, he is correct.No, he is incorrect. The answer should be 6.No, he is incorrect. The answer should be 9.None of the above

Answer 1

D. None of the above

Step-by-step explanation

We want to determine if x = 3 is the solution to the equation given:

`x^2=16`

To solve this equation, we have to find the square root of both sides of the equation (the solution will consist of a negative and positive number):

`\begin{gathered} x=\sqrt[]{16} \\ \Rightarrow x=+4;x=-4 \end{gathered}`

Therefore, Diego is incorrect but none of the reasons stated is correct.

Hence, the answer is None of the above.
