IS THE ANSWER 1, 3, 17, 57 or none of the aboveIf none of the above please write the correct answer!Please answer step by step explanation

Answer 1

ANSWER

None of the above.

EXPLANATION

We want to solve the equation given for x:

$\sqrt[]{x-1+5}=9$

First, simplify the radical:

$\sqrt[]{x+4}=9$

Now, find the square of both sides of the equation:

$\begin{gathered} (\sqrt[]{x+4})^2=9^2 \\ x+4=81 \end{gathered}$

Finally, simplify by subtracting 4 from both sides of the equation:

$\begin{gathered} x=81-4 \\ x=77 \end{gathered}$

Hence, the correct option is "None of the above".
