[tex]\begin{gathered} x^2=40 \\ \end{gathered}[/tex]
To solve this, you need to make this
Step 1
square root in both sides
[tex]\begin{gathered} x^2=40 \\ \sqrt{x^2}=\sqrt{40} \\ \text{the }\sqrt{\square}\text{ is eliminated by the exponent} \\ x=\sqrt{40} \end{gathered}[/tex]
Now, the two solutions for this are.
[tex]\begin{gathered} x=\sqrt{40} \\ x=-\sqrt{40} \\ \\ \end{gathered}[/tex]
so, the answer is
[tex]x=\pm\sqrt{40}[/tex]
I hope it helps you.
