ANSWER
None of the above.
Step-by-step explanation
We want to solve the equation given for x:
![\sqrt[]{x-1+5}=9](https://img.qammunity.org/2023/formulas/mathematics/high-school/wokxwt6gmvf4bdoyowl0xdjr0bpe7eu4ql.png)
First, simplify the radical:
![\sqrt[]{x+4}=9](https://img.qammunity.org/2023/formulas/mathematics/high-school/obll5zhqimidcx46rfx0bb65h592qnnczf.png)
Now, find the square of both sides of the equation:
![\begin{gathered} (\sqrt[]{x+4})^2=9^2 \\ x+4=81 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/9ftgzsqw3phc85aq443kf1bn0zkd80ql3w.png)
Finally, simplify by subtracting 4 from both sides of the equation:

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